Changes from 2007-08-01 onwards: see SourceForge git repository.

2005-12-21  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c (do_logo_invert): fixed previous "*ptr++=255-*ptr",
	which was obviously not too clever.

2005-12-18  Russell Marks  <russell.marks@ntlworld.com>

	* src/help.c (help_about): updated URL.

	* src/logoconv.c: another missing string.h.

	* src/resizepic.c: didn't include string.h previously, and should
	have.

2005-09-21  Russell Marks  <russell.marks@ntlworld.com>

	* src/readjpeg.c (read_jpeg_file): now supports YCCK/CMYK
	colourspaces, as can be written by e.g. Photoshop. Thanks to
	Michael Woerdehoff for pointing out the problem.

2004-12-15  Russell Marks  <russell.marks@ntlworld.com>

	* src/readpng.c (read_png_file): bizarrely, I missed the
	width/height limit on PNG before. :-( Added it now, thanks to
	Ludwig Nussel for pointing this out.

2004-11-03  Russell Marks  <russell.marks@ntlworld.com>

	* Added width/height limits to all native picture readers. This is
	a crude (albeit effective) fix for heap overflow bugs - there may
	yet be more subtle problems, but I can't really fix them until I
	know they're there. :-) Thanks to Luke Macken for letting me know
	about the heap overflow problems (in zgv). I suppose I should also
	thank "infamous41md" for publishing the original advisory/exploit
	(again for zgv), even if he didn't bother emailing me or anything.

2003-09-16  Russell Marks  <russell.marks@ntlworld.com>

	* Version 0.8.

	* src/help.c (help_about): now says what the program does. Which
	is probably rather obvious, but what the heck. :-)

	* src/main.c (viewer_expose): fixed long-standing bug with
	interpolation, which could have resulted in segfaults (though it's
	hard to say if it ever actually did).

	* src/rcfile.c (usage_help): removed embedded LFs.

	* src/readjpeg.c (get_exif_orientation): added support for the
	Exif orientation tag (Exif in this context is a form of JPEG). If
	you enable the "Use Exif Orientation" option in the viewer (or
	`exif-orient' config/option), it'll compensate for the (e.g.)
	digital camera's orientation when viewing, so pictures taken with
	the camera side-on will display the way you would probably want
	them to. However, since this differs from how most *other*
	programs will see the files - which are, after all, carefully
	constructed to be compatible with JFIF/JPEG files - and has the
	potential to be extremely confusing if you don't know exactly
	what's going on, it's not enabled by default. Thanks to Fraser
	Wright for suggesting this feature.

2003-07-10  Russell Marks  <russell.marks@ntlworld.com>

	* src/readpng.c (read_png_file): don't set background colour to
	black for mono PNG files, where this may cause problems. This
	change was ported from zgv; thanks to Morten Bo Johansen for
	spotting it there.

2003-04-05  Russell Marks  <russell.marks@ntlworld.com>

	* doc/makeman.awk: fixed some bugs which became apparent when run
	with gawk 3.1.

2003-02-01  Russell Marks  <russell.marks@ntlworld.com>

	* INSTALL: added report of MacOS X compile, from
	krisa@subtend.net.

2002-08-22  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c (selector_key_press): added 9/0 as yet another way of
	doing file untag/tag. These are last-ditch alternatives for
	keyboards where -/= don't make sense (some non-US/UK keyboards),
	and where keypad -/+ aren't easily accessible (e.g. laptops).
	Thanks to Szab, Balzs for inspiring this one.

2002-07-25  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c (main): added call to gtk_set_locale() which should
	hopefully avoid problems when GTK+'s default font is set to
	something which isn't ASCII-friendly. Thanks to Alexander Pohoyda
	for this one.

2002-07-09  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c (cb_hide_selector): stopped selector getting
	permanently hidden if two middle-button presses were too close
	together. Thanks to Jos Luis Gonzlez Gonzlez for spotting this.

2002-03-03  Russell Marks  <russell.marks@ntlworld.com>

	* src/readgif.c (outputstring): broken GIFs could overrun a buffer
	previously - fixed.

2002-01-16  Russell Marks  <russell.marks@ntlworld.com>

	* INSTALL: added IRIX success report. Thanks to Andreas Backhaus.

2002-01-01  Russell Marks  <russell.marks@ntlworld.com>

	* src/readjpeg.c (read_jpeg_file): fixed post-image corruption
	bug, so it shouldn't segfault now. (!) Now it should ignore any
	errors which come after we've got an image (based on the idea that
	since we do *have* an image, we should display it). Thanks to
	Aaron Brick for spotting this one.

2001-10-24  Russell Marks  <russell.marks@ntlworld.com>

	* INSTALL: added Solaris success report. Thanks to Sven Goldt for
	that. [And to Steven Bankowitz, who also reported success.]

2001-09-20  Russell Marks  <russell.marks@ntlworld.com>

	* src/rcfile.c (usage_help): fixed typo.

2001-04-10  Russell Marks  <russell.marks@ntlworld.com>

	* Version 0.7.

	* src/Makefile: whoops, `-lz' was missing. I usually got away
	with this, but it did break in some cases (perhaps with Imlib
	1.9.10?). Thanks to Gabor Z. Papp for pointing this out
	(albeit, again, somewhat indirectly :-)).

	* src/mkopts.awk: there isn't any reason I can't just use stdout
	for error messages, so do that.

	* src/updatetn.c (cb_update_tn): this'll be fun to explain. :-)
	Ok... the non-recursive thumbnail update stops thumbnail reading
	before doing the update (as does the recursive one, but never mind
	that). Previously, if you pressed `u' soon enough after the
	thumbnail-read had started, and only files a long way down in a
	big directory needed new thumbnails, then you could be left with a
	mostly-blank set of thumbnails onscreen for (say) a few seconds.
	It now makes sure all thumbnails in the visible portion of the
	list are read before it starts, rather like recursive update.

	* src/backend.c: marking image as uncacheable seems to *very*
	occasionally lead to a segfault (infrequently enough that I've
	found this hard to track down), apparently due to unearthing a bug
	in Imlib1's uncacheable-image code which is (I think) never
	otherwise used. So we don't do that any more.

2001-04-09  Russell Marks  <russell.marks@ntlworld.com>

	* Added support for PRF (ported from zgv), which is basically a
	kind of extrapolated version of my old mrf format - unlike mrf,
	PRF supports greyscale and colour. Thanks to Brian Raiter for both
	devising the format, and writing the reference implementation
	readprf.c is heavily based on.

	* src/mkopts.awk: now detects running under an old awk, and
	complains about it with a pointer to config.mk.

2001-03-01  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: toggling all tags is now possible, with Alt-o or
	Tagging/Toggle All.

	* src/main.c: you can now move to the next/previous tagged file
	with `/' and `?' respectively (or equivalent menu options). When
	used in the viewer, this also views the file.
	(init_window): moved `Tag then Next' to new viewer `Tagging' menu.

	* src/main.c: fix for redraw-related position problem. (In 0.6,
	try going to the end of the selector's list, pressing `v', then
	pressing `v' again - the row positioning is slightly wrong.)
	(init_window): added `Open' to selector `File' menu, and
	rearranged the menu slightly; moved tagging commands to `Tagging'
	menu.

2001-02-03  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c (set_title): no longer includes the version number in
	the window title, as you can get this from both `xzgv --version'
	and About on either Help menu.

	* Added help menus. Currently just runs info on the relevant node,
	but it's better than nothing I s'pose. :-)

2001-01-16  Russell Marks  <russell.marks@ntlworld.com>

	* Added choice of timestamps to use when sorting in time/date
	order - you can now choose mtime (default), ctime, or atime. You
	can switch with alt-shift-m/c/a, or from selector menu's
	Directory/Time & Date Type submenu, or with `sort-timestamp-type'
	option/config. Thanks for Wolfram Kleff for suggesting this.

	* src/main.c (viewer_key_press): you can now use shifted cursor
	keys as an alternative means of paging up/down/left/right in the
	viewer.
	(selector_key_press): any `Menu' key you might have can now be
	used to show the selector/viewer menus, just as right-clicking or
	pressing F10 does.

2000-12-28  Russell Marks  <russell.marks@ntlworld.com>

	* src/readtiff.c: didn't need to include rcfile.h.
	(read_tiff_file): previously flipped the image incorrectly.

2000-12-21  Russell Marks  <russell.marks@ntlworld.com>

	* `make install' now uses slightly more friendly Debian-ish
	permissions (755 for executable, 644 for docs).

2000-12-15  Russell Marks  <russell.marks@ntlworld.com>

	* src/readgif.c (outputstring): copied new non-recursive
	outputstring() across from zgv. No real advantage in xzgv, but
	it saves a gratuitous inconsistency at least. :-) Oh,
	actually, there is an advantage - this version shouldn't be
	hangable even with badly broken GIFs.

2000-12-14  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c (cb_selection): made toggles which could possibly
	affect the image display (in fact, did just about any which do
	GTK+ stuff) ignore the toggle attempt if currently loading an
	image. The main problem this fixes is the weirdness that used to
	happen after toggling zoom while a picture was loading
	(particularly when unzooming, and loading a `big' picture).

2000-12-13  Russell Marks  <russell.marks@ntlworld.com>

	* src/readgif.c (decompress): inittable() shouldn't have trusted
	code size to match numcols. It broke on a certain flavour of
	unusual and suboptimal, but valid, GIF with less than 256 colours
	(probably generated by a `broken' encoder). Thanks to Lenart
	Janos, Josip Rodin, and Chris Lawrence for spotting this and/or
	pushing the bug report to your friendly neighbourhood upstream
	maintainer. :-)

	* src/readjpeg.c (read_jpeg_file): sped things up a bit by reading
	in a slightly less simplistic manner, and by not doing "fancy
	upsampling" (doing this previously was the main reason why
	Imlib1's reader was faster). Combined with the change below, this
	makes native JPEG reading a teeny bit faster than Imlib1's, so
	it's now done that way for non-thumbnail use too. Also added
	`careful-jpeg' option/config, in case you want to leave it
	enabled (seems to be about a 10% slowdown).

	* src/backend.c (backend_create_image_from_data_destructively):
	now properly implemented for Imlib1. The way I've done it is
	slightly evil, but it speeds things up. ;-)

	* doc/xzgv.texi (File Type Identification): this bit could
	probably do with a rewrite, but at least it vaguely resembles
	reality now. :-)

	* src/readtiff.c: TIFF reader - uses libtiff. This means yet
	another library dependancy :-/, but enough people seem to use xzgv
	with TIFFs that it's probably worth doing properly.

2000-12-10  Russell Marks  <russell.marks@ntlworld.com>

	* src/updatetn.c (update_one_tn): now makes sure a page of
	thumbnails is visible even when doing non-recursive update -
	previously doing such an update before all thumbnails had been
	read in would show blank spots during the update (unlike the
	now-usual xzgv behaviour of loading onscreen thumbnails asap).
	This only seems to slow it down fractionally (by about 0.5% in a
	large dir full of small files in thin-rows mode), so I think it's
	worth it to get the consistency.

2000-11-24  Russell Marks  <russell.marks@ntlworld.com>

	* INSTALL: added more 0.6 success/failure reports - thanks to
	Joerg Reuter at SuSE.

	* src/main.c (viewer_key_press): whoops, I broke alt-a/u from
	viewer when I added ^a/^u - sorted that out.

	* src/backend.c: added gdk-pixbuf backend (aimed at 0.9.0).
	gdk-pixbuf doesn't quite provide everything xzgv needs, and seems
	rather slower than Imlib1 at rendering *despite* avoiding some
	unnecessary pixmap creation, so I don't see myself recommending
	use of this any time soon. Anyway, it's there if you want to try
	it. It doesn't support flip/mirror/rotate, or any
	brightness/contrast/gamma changes (I suppose I'll get around to
	these eventually, but expect them to be *slow* as gdk-pixbuf
	doesn't provide native facilities for this stuff), and doesn't
	support as many filetypes as Imlib1 (no fallback I suppose), but
	the rest is there.

2000-11-23  Russell Marks  <russell.marks@ntlworld.com>

	* src/readjpeg.c: adapted readjpegtn.c so it's usable as a normal
	JPEG reader too. Unfortunately this seems to be slower than Imlib1
	at reading JPEGs :-) (probably because creating Imlib's image from
	the RGB data involves copying it?), so it's still only used for
	thumbnails.

	* src/main.c (cb_delete_file): added `delete-single-prompt'
	option (cmdline and config file) so you can disable the y/n
	prompt when deleting a file, rather like zgv's `nodelprompt'.
	Thanks to Martin Bialasinski for suggesting this.

2000-11-21  Russell Marks  <russell.marks@ntlworld.com>

	* doc/xzgv.texi: case of chars in Alt-x and Ctrl-x forms should
	now be uniformly lowercase.
	(File Details): now mentions problem with zgv 5.0/5.1 generating
	incorrect thumbnail width/height details (5.2 is ok).

	* src/main.c: many keyboard navigation fixes/additions. Selector
	and viewer now both support ^u/^v/^a/^e as alternatives to page
	up/down and home/end. j/k in selector were fixed to behave more
	like cursor up/down do.

2000-11-20  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: concerted attempt to nail all the remaining
	recursion problems. Now everything which even *thinks* of calling
	render_pixmap() is protected. :-) This isn't perfect though, as
	the protections are independent (do a mirror and flip at about the
	same time, and it'll mess up), so I'll need a better fix
	eventually.
	(do_gtk_stuff): this is now a LOT smarter about what to do when
	thumbnails are being loaded - fixes the bug where (while
	thumbnails were being loaded) holding down space to storm through
	N images got it very confused indeed.

	* doc/xzgv.texi (Renaming a File): it's xzgv not zgv. :-)

	* src/main.c (load_image): X windows are limited to a maximum size
	of 32767x32767 pixels, and xzgv uses a GTK+ widget based on an X
	window for its image. That's not the change, this is - previously,
	my GIF/PNG/mrf file readers failed to notice the problem larger
	images would cause, leading to a segfault - they now give an
	error.
	(cb_selection): now ensures focus is returned to selector when
	changing dir, making the pastpos action clearer when using the
	mouse (i.e. if you go down into a dir and then back up, the
	keyboard cursor will show which dir you just left). Previously, if
	you'd viewed an image before changing dir with the mouse, focus
	would have remained on the image.

	* src/updatetn.c: recursive thumbnail update no longer reads all
	thumbnails before doing updates - it now only bothers to read
	visible thumbnails. This makes the `fast-recursive-update' option
	rather less useful, as it's nearly that fast already. :-)
	(cb_update_tn_recursive_confirmed): previously didn't do pastpos
	stuff to save/restore cursor row `around' recursive update -
	fixed.

2000-11-17  Russell Marks  <russell.marks@ntlworld.com>

	* Now adapts rendering method for big images. When the number of
	pixels in the image exceeds the value set by
	image-bigness-threshold (as set in config file or on command-line,
	defaulting to 2 million pixels), it's drawn piece-by-piece on
	demand rather than all-at-once. The all-at-once behaviour is worth
	keeping around for smaller images, as it gives much nicer
	scrolling - but for big images it's just impractical, hence this
	feature.

	* src/main.c: previously, when you scaled down as far as it would
	go, it would never let you scale down again in the same way, due
	to breaking an anti-recursion measure. Fixed that.

2000-11-16  Russell Marks  <russell.marks@ntlworld.com>

	* src/backend.c: wrapper for rendering backend. This is now (apart
	from the Makefile) the only place with any Imlib1 dependence, so
	this should make it easier (or rather, slightly less than
	infinitely hard :-)) to switch backends if I decide to do that, or
	to support multiple backends (choosing backend at compile time).

2000-11-11  Russell Marks  <russell.marks@ntlworld.com>

	* doc/Makefile: replaced ifeq/ifneq with shell equivalent, which
	turns out to be sufficient (if uglier). This should avoid the need
	to use GNU make. Thanks to Frank Pohl for spotting this problem.

2000-11-07  Russell Marks  <russell.marks@ntlworld.com>

	* Changed `install -m' invocations to do plain install and change
	permissions after (with chmod). Thanks to Steven Bankowitz for
	reminding me of `-m' being a problem on things like Solaris.

2000-10-29  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c (init_window): as must be traditional by now, I found
	a bug almost immediately after the release. :-) Quite a minor one,
	thankfully. Previously you could still toggle thin-rows while
	running in the `xzgv file(s)' way, which was silly and made things
	look strange. Harmless, but fixed now.

2000-10-28  Russell Marks  <russell.marks@ntlworld.com>

	* Version 0.6.

2000-10-27  Russell Marks  <russell.marks@ntlworld.com>

	* src/filedetails.c (make_details_win): file details dialog now
	works fully even when started with `xzgv file(s)' (previously the
	details from any thumbnail were missing).

2000-10-26  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c (cb_selection): before, when you used decoupled
	scaling and then rotated a picture, it messed up when resetting
	things for the next picture. Fixed that. (It swapping the scalings
	inappropriately when setting picture orientation to either 0 or
	the last picture's state.)
	(reinit_dir): when rescanning the directory (in the control-r
	sense :-)), the keyboard cursor now tries to stay at the same
	place in dir list, for consistency with zgv and because it's just
	nicer. Thanks to Philippe Marzouk for spotting this one.

	* TODO: made into an outline to keep the less important stuff from
	crowding out the things I should really be thinking about.

2000-10-25  Russell Marks  <russell.marks@ntlworld.com>

	* doc/makeman.awk: previously, a one-line paragraph with a
	formatting-type @-command would merge into the start of the next
	paragraph.

	* src/readgif.c (outputchr): was previously broken for interlaced
	GIFs with less than 4 lines; this broke the heap, leading to
	difficult-to-pin-down segfaults.

	* INSTALL: generally updated and tidied up. Also added a section
	reporting how past versions of xzgv (currently 0.5) have been said
	to react on certain non-Linux/x86 systems.

2000-10-23  Russell Marks  <russell.marks@ntlworld.com>

	* src/copymove.c: now copes with copy/move when started as `xzgv
	file(s)'. It's not perfect, in that the selector isn't updated (so
	after a move things can be confusing), but at least it's usable.

	* Made icon a bit less indistinct. :-)

2000-10-22  Russell Marks  <russell.marks@ntlworld.com>

	* You can now change the sorting order from the command-line with
	`-o'/`--sort-order' (and from a config file similarly), which
	takes a name/ext/size/date (or time) arg (though only the first
	char is required).

	* src/rcfile.c: if you omitted the arg to an option in a config
	file, it would segfault. Fixed that, and applied brown paper
	bag as appropriate. :-)

	* src/rcfile.c (usage_help): usage help is now strictly sorted in
	long-option order.
	(geom_parse): would previously get stuck in an infinite loop if
	given a bogus geometry arg.

2000-10-17  Russell Marks  <russell.marks@ntlworld.com>

	* Added my own PNG reader (well, libpng interface :-)), ported
	from zgv. This avoids the Imlib PNG problems (still present in
	1.9.8, the latest version I've checked), such that greyscale
	PNGs are now read correctly, and you no longer have the `now
	it's purple, now it's not' problem with partly-transparent
	PNGs. (Though that does still affect, for example, XPMs.) It
	also seems to be slightly faster, but only very slightly. So
	note that you now need to have png.h and pngconf.h available
	when compiling xzgv (you already needed the *library* for
	Imlib, but now you need the headers too).

2000-10-10  Russell Marks  <russell.marks@ntlworld.com>

	* doc/makeman.awk: ported over zgv change - previously it didn't
	output a correct NAME line (it used "-" rather than "\-").

2000-10-07  Russell Marks  <russell.marks@ntlworld.com>

	* Since I've finally switched to using Emacs's c-mode, after
	getting the indentation configured correctly with no bugs
	getting in the way (I hope :-)), I've reindented everything
	(other than getopt* and install-info.c) with it. The changes
	are minor, obviously - essentially it's just lining things up
	a bit more nicely, though some long lines in main.c had to be
	mangled a bit to keep the line length under 80 chars.

2000-09-30  Russell Marks  <russell.marks@ntlworld.com>

	* src/rcfile.c: get_config() previously assumed $HOME was set.

2000-09-25  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: added gamma support, but as with brightness/contrast
	this is only available from the keyboard for now. The basic idea
	is to ignore the rather unworkable image/screen gamma distinction,
	and just use a relative gamma with fast shortcuts for common
	cases. So pressing `1' gives a gamma adjustment of 1.0 (i.e. no
	adjustment), `2' gives 2.2 (for e.g. viewing linear-gamma files on
	an average PC monitor), `3' gives 1/2.2 (~0.45, for e.g. viewing
	2.2-gamma files on a linear-gamma display), and `4' reverts to any
	`--gamma' setting (or 1.0 if none was set). You can also use
	alt-comma and alt-dot for more precise control of gamma
	adjustment. Note that gamma is deliberately *not* reset by the
	brightness/contrast resetting keys.

2000-08-26  Russell Marks  <russell.marks@ntlworld.com>

	* doc/xzgv.texi (Invoking xzgv): --zoom-reduce-only line should
	have been an `itemx' not an `item'.
	(Rescanning the Directory): rephrased to avoid awkward repetition
	of `however'.

	* Changed `$(MAKE) -C foo bar' in Makefiles to the more portable
	form `cd foo && $(MAKE) bar'.

	* Unfortunately doc/makeman.awk really does require gawk (some
	features of gensub are too difficult to do without), so I've
	changed the Makefiles such that a prebuilt man page will come with
	the xzgv tgz. This doesn't make the tgz much larger, and seems a
	tolerable compromise for coping with gawkless systems.

2000-08-24  Russell Marks  <russell.marks@ntlworld.com>

	* src/Makefile: install-info uses getopt_long(), so it needs to
	link with getopt.o and getopt1.o to avoid problems on non-glibc
	systems. Thanks to Steven Bankowitz for the feedback on a Solaris
	build which lead to this fix (and those below).

	* src/install-info.c: now uses the bundled getopt.h rather than
	assuming there's one on the system.

	* config.mk: added AWK line, so you can specify the awk
	interpreter to use. (A `new' awk is needed, so gawk is the
	default, but nawk is another possibility.) This setting doesn't
	yet apply to doc/makeman.awk, which is currently hardcoded to use
	gawk since it requires a gawk extension. (One to fix later, I
	suppose. :-))

2000-08-17  Russell Marks  <russell.marks@ntlworld.com>

	* Version 0.5.

2000-08-15  Russell Marks  <russell.marks@ntlworld.com>

	* logo.c: whoops, still had a zgv header, fixed that. :-)

	* TODO: checked up on does-this-still-happen bugs - most do still
	happen. They're not major ones, I s'pose, but it's enough for the
	next version to be 0.5 rather than the 1.0 I'd been considering.
	:-/

	* src/main.c: made the thumbnail loading's jumping-about
	behaviour considerably smarter - it should be pretty optimal
	now (given the requirement that it jump around to show
	currently-visible stuff, that is).

2000-08-04  Russell Marks  <russell.marks@ntlworld.com>

	* src/libmmx-990416/mmx.h: fixed so it compiles even with
	optimisation off, though I can't imagine why you'd compile it like
	that. :-) Thanks to Gabor Z. Papp for pointing this out (albeit
	somewhat indirectly).

2000-07-25  Russell Marks  <russell.marks@ntlworld.com>

	* src/gotodir.c: previously, jumping from a large dir to a large
	dir (or even to a small dir, sometimes) could result in the
	redrawing of the main window being noticeably delayed after the
	dir-change window being destroyed - fixed that (mostly).

2000-07-24  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: massively reduced *apparent* thumbnail load time, by
	making it jump around to whichever part of the directory you're
	currently looking at. :-) (It will eventually fill in any gaps,
	when you stop moving around for long enough.)

2000-07-13  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: added preliminary check when reading files from
	command-line, to get rid of (at least in most cases) the
	window-open-then-close ugliness you used to get before a `no
	files' error message.

2000-07-11  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: rows have been made 2 pixels taller, to allow room
	for the outline cursor to go either side of the thumbnail rather
	than potentially XORing over it. In addition to being a little
	more aesthetically pleasing :-), this works around what seems to
	be a GTK+ bug (as of 1.2.7 at least), where scrolling with the
	cursor keys can leave part of the XOR'd cursor outline stuck on
	the thumbnail (I suspect the pixmap is being drawn at the wrong
	time). The extra pixel lines reduce the number of thumbnails
	visible at once very slightly, which is unfortunate, but I really
	think it's necessary.

2000-07-10  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: fixed recursion problems in scaling. Thanks to
	Steven Flintham for reminding me of this, and noting how badly it
	affected decoupled scaling.

2000-07-04  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: anti-clockwise rotation previously didn't swap x/y
	scaling values, so when using decoupled scaling it screwed up.

2000-06-28  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: fixed a significant memory leak, though you probably
	wouldn't have noticed it unless you did a recursive thumbnail
	update on a fairly well-populated hierarchy. I have a feeling this
	fix *may* break older GTK+ versions; if changing directory
	segfaults, you need to upgrade. :-) It's known to work on at least
	GTK+ >=1.2.6.

2000-06-27  Russell Marks  <russell.marks@ntlworld.com>

	* doc/xzgv.texi: finally got around to documenting decoupled
	scaling stuff. :-)

	* doc/xzgv.texi (Viewer Options): listed keyboard shortcut for
	zoom-reduce-only was wrong.

	* src/options.src: added short option `-r' for zoom-reduce-only.
	It's a useful enough option that it's worth having a shortcut. :-)

	* src/main.c: added mouse shortcut for decoupled scaling. This is
	quite a tricky one on the UI front, but the basic idea is that you
	can scale only one axis directly from the mouse, as it were, with
	ctrl-click and ctrl-right-click. You can change the axis to scale
	(default is the Y axis) by using the axis toggle on the viewer
	options menu (or by pressing alt-c). You can change the default by
	enabling `mouse-scale-x', on the cmdline or in a config file.

2000-06-08  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: added decoupled scaling - you can now scale x and y
	axes of a picture independently. Thanks to Steven Flintham for
	suggesting this. It's primarily for fixing aspect ratios on pics
	intended for viewing with non-square pixels. Interpolation isn't
	supported when the x scale doesn't equal the y scale.

2000-05-11  Russell Marks  <russell.marks@ntlworld.com>

	* config.mk: changed back to using -O2. It seems this doesn't
	break anything any more. Presumably I'm now avoiding whatever
	compiler bug was probably responsible for problems before. :^)

2000-05-06  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: clicking on the viewer now moves to the next
	image. Dragging the picture around still works - any mouse
	movement at all during the click, and the picture gets dragged
	instead. (If you want/need to disable this for some reason,
	you can do so with `click-for-next off' in ~/.xzgvrc.) Thanks
	to Paul E. Johnson for this idea.

2000-05-03  Russell Marks  <russell.marks@ntlworld.com>

	* src/main.c: previously, if you had auto-hide and zoom turned on,
	then turned off auto-hide, the picture wasn't rezoomed when the
	selector was shown - fixed that.

	* src/libmmx-990416/mmx.h: fixed to work with gcc 2.95.x. Had to
	remove eax from clobber list in mm_support(), and get rid of some
	spurious colons after instructions. It now compiles
	(and seems to work ok) with -DINTERP_MMX on at least three
	different versions of gcc (thanks to Steven Flintham for testing
	two of them :-)).

2000-04-23  Russell Marks  <russell.marks@ntlworld.com>

	* Updated email address everywhere (except below).

2000-04-14  Russell Marks  <russell.marks@dtn.ntl.com>

	* config.mk: now easier to install info file/man page in
	FHS-friendly PREFIX/share (e.g. /usr/share/man/man1). However, the
	traditional locations are still the default, as I suspect e.g.
	/usr/local/share/man/man1 is much less widely accepted than
	/usr/local/man/man1. If you're installing in /usr, though,
	uncommenting the SHARE_INFIX line may be a good idea.

2000-03-31  Russell Marks  <russell.marks@dtn.ntl.com>

	* Version 0.4.

	* README: removed mrf stuff which I suspect no-one cared about in
	the first place. (Even I was getting tired of it, and I *use*
	mrf... :-))

2000-03-14  Russell Marks  <russell.marks@dtn.ntl.com>

	* doc/xzgv.texi: documented cut/copy/paste in `goto dir' dialog.

	* doc/xzgv.texi (Moving Around The List): removed link from after
	"Mouse-happy types can freely skip it" comment, as it wasn't that
	useful and would have looked odd in a printed copy... :-)

	* src/main.c: you can now use j/k for down/up in the selector, as
	vi-like alternatives to the cursor keys.

2000-03-12  Russell Marks  <russell.marks@dtn.ntl.com>

	* src/main.c: added brightness/contrast, which works in just the
	same way as in zgv. No mouse equivalent yet though, as I'm having
	some difficulty thinking of a reasonable way to do it. (I may even
	end up (ab)using a modal dialog for it, which would be *odd* but
	may be the least unreasonable approach given the way xzgv works in
	general.) I'd ended up putting it off for a while to ponder this,
	but in the end decided to get it done and add the mousey version
	later.

	* src/main.c: now avoids a malloc()/free() for each thumbnail
	read. I doubt it makes much difference to anything though.

2000-03-08  Russell Marks  <russell.marks@dtn.ntl.com>

	* INSTALL: updated to reflect MMX change, and asked for feedback
	regarding portability.

	* config.mk: disabled INTERP_MMX by default, as libmmx doesn't
	seem to compile under a newer gcc/egcs, and there was no newer
	libmmx when I last checked, *and* I can't easily try fixing this
	myself until I'm running 2.95.* or whatever. :-/

2000-03-07  Russell Marks  <russell.marks@dtn.ntl.com>

	* doc/xzgv.texi (Invoking xzgv): de-biased bit which mentioned
	GNOME in passing to mention both GNOME and KDE, as both are
	equally valid in context.

	* src/main.c: 15/16-bit dithering can now be toggled with shift-f,
	by analogy with zgv's `fakecols' toggle.

2000-03-03  Russell Marks  <russell.marks@dtn.ntl.com>

	* src/main.c: fixed the problem with toggling zoom off and on
	quickly, where scrollbars were disabled but an unzoomed image was
	shown instead of a zoomed one. This was due to recursion in
	toggle_zoom(), which is now avoided.

2000-02-11  Russell Marks  <russell.marks@dtn.ntl.com>

	* I now actually bother using my email address for changelog
	entries. :-)

	* src/main.c: renamed `Exit viewer' menu item to `Exit to
	Selector', which should make the meaning less ambiguous.

	* TODO: slightly tidied up and checked/updated.

2000-02-05  Russell Marks  <rus@cartman>

	* README: looks like I left this on 0.2 for 0.3, whoops :-)

	* src/main.c: added file rename. The key it's on is heavily
	suboptimal (^n), but all the good ones were taken. :-) Menu-wise
	it's ok though - File/Rename file (by analogy with the
	delete-single-file one).

	* src/rename.c: created.

2000-02-03  Russell Marks  <rus@cartman>

	* src/main.c: file magic tests in load_image() supplied 4 bytes to
	test, but only bothered testing 3. :-)

2000-01-29  Russell Marks  <rus@cartman>

	* src/updatetn.c: now avoids the nasty `shear' effect you got when
	updating thumbnails and it needed to scroll the window before
	updating a thumbnail.

2000-01-14  Russell Marks  <rus@cartman>

	* Version 0.3.

	* src/config.mk: changed CFLAGS to use -O instead of -O2 (I
	actually did this a few days back); Steven has had weird problems
	with a recent gcc with -O2, but -O works. (I seem to be ok with
	(according to `gcc --version') egcs 2.91.66, but it's easier to
	just throttle back than have it screw up. Besides, all this really
	does is slow down scaling a bit.)

	* Removed mention of the forfree.at email address, which seems to
	be b0rken :-(, and replaced with my actual current address.

	* INSTALL: removed note about needing getopt_long().

	* Added getopt.[ch] and getopt1.c from glibc, so things should
	hopefully still work on a libc which lacks getopt_long().

2000-01-10  Russell Marks  <rus@cartman>

	* src/copymove.c: use pastpos to try and stay in similar place in
	selector when rescanning dir. It isn't perfect - in particular, if
	the old row no longer exists it goes to row 0 rather than staying
	at the end - but it's better than *always* going to row 0.

2000-01-09  Russell Marks  <rus@cartman>

	* src/copymove.c: added copy/move. These work like zgv - copy/move
	tagged files if any tagged, otherwise copy/move the file the
	cursor is on. (Being zgv-like also means they stop if they run
	across an existing file, which can be a little annoying but is
	probably safest.)

	* src/gotodir.c: made cb_ok_button() static.

1999-12-19  Russell Marks  <rus@cartman>

	* src/main.c: you can now use `-k' or `--skip-parent' (or config
	file entry) to skip the (keyboard) cursor past `..' on the
	directory xzgv starts on. This can be useful when you want to
	immediately use space to `page' through a dir. Thanks to Steven
	Flintham for this idea.

1999-12-14  Russell Marks  <rus@cartman>

	* src/main.c: the idle_zoom_resize() idle func is now default
	priority rather than resize priority. This fixes a problem where
	zoom mode resizes were one resize behind (!) - thanks to Steven
	Flintham for pointing this out. Unfortunately this makes `opaque
	resize' a bit slower, but I think this fix is clearly the Right
	Thing.

1999-12-13  Russell Marks  <rus@cartman>

	* doc/makeman.awk: fixed spurious blank line output in middle of
	@item/@itemx pairs when there was a comment line between them.
	It's a pretty ugly kludge, but I couldn't really see any other fix
	which wouldn't break something else. :-/

	* src/main.c: scaling can now scale the image *down* as well as
	up. That is, you can make the image smaller more controllably than
	you can by using zoom mode. I thought I'd add this as, given the
	way Imlib works, it comes very cheaply indeed. However, it tends
	to only be useful (i.e. be any advantage over zoom mode) on big
	images, where you might want to scale down a bit rather than a
	lot. One thing I should point out - if you've got used to doing
	e.g. shift-d lots to get back to 1:1, you'll just have to learn
	about the `n' (= Scaling/Normal) key... :-)

	* src/main.c: invert-logo now kludges the bottom/rightmost lines
	of the logo (which are black in the original, and thus turn white)
	to be a more appropriate grey. A miswart, essentially - it's
	horrible, but probably the Right Thing in context. :-)

1999-12-10  Russell Marks  <rus@cartman>

	* AUTHORS: created. Just points at the main docs, I'm sure a
	duplicate copy would get out of date. :-)

1999-12-09  Russell Marks  <rus@cartman>

	* src/main.c: various things which implicitly turned off zoom mode
	(basically scaling and `normal') didn't reenable scrollbars
	afterwards; fixed that.

1999-12-08  Russell Marks  <rus@cartman>

	* src/main.c: new `invert-logo' config file option, flips the
	colours in the logo to look less awful on dark GTK+ themes. :-)
	The obvious way to `fix' this is to provide some way of disabling
	the logo, but at the moment it assumes there's always a picture in
	the viewer window, so this is a bit hairy. (And I think it looks
	odd with the viewer window empty, which is the reason I bothered
	with a logo in the first place!)

1999-12-06  Russell Marks  <rus@cartman>

	* src/main.c: added MMX-aware version of scaling with
	interpolation code (using a bundled copy of Hank Dietz/Randy
	Fisher's libmmx). According to my tests, it's `only' about 35%
	faster, but it feels like more. :-) See config.mk for details.

	* src/rcfile.c: you can now set the selector's initial/default
	width with `--selector-width' (or config file setting). It can
	only be specified in pixels for the time being, but I should add a
	percentage option at some point. :-)

1999-11-30  Russell Marks  <rus@cartman>

	* doc/xzgv.texi (Config Variable Types): added `geometry', which
	was missing, and corrected previous bit which said all config vars
	were boolean.

1999-11-22  Russell Marks  <rus@cartman>

	* Version 0.2.

	* Made install targets use `mkinstalldirs' (from texinfo) to make
	paths to installation dirs first. Apparently the FHS guarantees
	little if anything about /usr/local, so this is basically required
	rather than merely being a good idea. I've left `mkinstalldirs'
	non-executable (and run /bin/sh on it directly from the
	Makefiles), as I don't like the idea of having a single executable
	file in the top-level dir (some people might think it's like a GNU
	configure script or whatever, and run it :-)).

1999-11-16  Russell Marks  <rus@cartman>

	* src/main.c: some fixes to avoid unwanted recursion when e.g.
	space is being held down. There still seem to be problems with
	this when you're really hammering it though (space held down for a
	long time in a dir with many small images).

1999-11-13  Russell Marks  <rus@cartman>

	* src/main.c: now have a reduce-only option for zoom mode, meaning
	you can have xzgv fit big pictures to the window without having
	tiny icons etc. balloon up and look horrible. It's not the
	default, but you can enable it with Alt-r or the viewer options
	menu's "When Zooming Reduce Only" toggle or `--zoom-reduce-only'
	or equivalent config file setting. Thanks to Steven Flintham and
	Robert Braddock for this idea.

1999-11-12  Russell Marks  <rus@cartman>

	* doc/xzgv.texi (Invoking xzgv): missed out `geom' arg after `-g'
	previously, fixed that.

1999-11-06  Russell Marks  <rus@cartman>

	* doc/xzgv.texi (Acknowledgements): added a credit for
	`install-info', which *seems* to have been largely written by Karl
	Berry, though it's not terribly clear (e.g. the initial change log
	entry is by RMS, but it just says "new file" or similar, so I'm
	assuming he didn't do a great deal :-)).

1999-11-04  Russell Marks  <rus@cartman>

	* src/main.c: fixed bug where, if you enabled zoom on a picture of
	nearly the same shape as the viewer window, it left the scrollbars
	on.

1999-11-03  Russell Marks  <rus@cartman>

	* src/main.c: you can now set whether to use 15/16-bit dithering
	or not independent of Imlib's default setting. The option is
	Options/Dither in 15 & 16-bit (guess who's using item_factory :-))
	on the viewer menu, and can also be set by --dither-hicol or
	equivalent config file setting.

1999-11-01  Russell Marks  <rus@cartman>

	* src/rcfile.c: added `-g'/`--geometry' option (and config file
	setting), which lets you set the xzgv window's geometry in the
	usual X fashion. As an extension, all positions/sizes can be given
	as percentages of the screen size - for example, the default
	geometry is `92%x85%'.

1999-10-31  Russell Marks  <rus@cartman>

	* src/main.c: no longer keeps saying "Reading file..." on
	statusbar if a file couldn't be read.

	* src/main.c: error dialogs now use an Ok button a third the width
	of the window, so they look a bit more like the other dialogs.

	* src/updatetn.c: made recursive update require confirmation.
	There's some annoyance value to this, I suppose, but I think it's
	justified. It really *can* take a long time, after all, and the
	dialog also explains what `recursive update' actually means; I
	think this is useful as it's a term some non-programmers are
	unlikely to be very familiar with.

	* src/main.c: added file delete (with confirmation), as
	File/Delete and ctrl-d. I couldn't seem to figure out how to get
	it bound to Delete (and the hairy and somewhat religious
	Backspace/Delete mapping area is probably best avoided anyway). I
	did consider putting it on shift-d like in zgv, but I thought the
	clash with shift-d as used in the viewer made this potentially a
	bad idea. (Also, ctrl-d has a `delete' meaning in various other
	things (e.g. Emacs), while shift-d is probably only used for this
	by zgv.)

	* src/confirm.c: generic confirmation (yes/no) dialog.

1999-10-27  Russell Marks  <rus@cartman>

	* Added recursive thumbnail update. One problem with this is that
	it reads all existing thumbnails in a dir before updating (like
	xv, IIRC) to try and avoid having a really ugly selector during
	the update :-), though you can disable this with
	`--fast-recursive-update' or an equivalent config file line.

	* src/updatetn.c: moved thumbnail-update stuff here, and removed
	extra GTK+ update from makexv332(), which was causing problems (it
	usually segfaulted if you destroyed the main xzgv window while
	updating thumbnails).

1999-10-26  Russell Marks  <rus@cartman>

	* src/main.c: now copes with being started in an unreadable dir,
	and avoids selecting files/dirs it doesn't have sufficient
	permissions for.

1999-10-25  Russell Marks  <rus@cartman>

	* src/main.c: you can now tag an image while viewing (like in zgv)
	by doing ctrl-space (not like in zgv :-)). Also on viewer menu
	after next/previous image.

	* src/resizepic.c: added a similar speedup which should work
	for any file type - it's not quite as fast as the JPEG
	approach, which is only really applicable to JPEGs, but it
	speeds things up a *lot* for non-JPEGs. It does mean that
	thumbnails for dithered images don't usually look as good as
	before, but you could probably argue that this makes them more
	faithful. :-) (Ok, I realise this could be annoying, so this
	speedup will probably become optional at some point...)

	* src/readjpegtn.c: custom JPEG loader for thumbnails, makes them
	as fast to generate as in zgv (well, curiously, it works out
	faster in xzgv for, uh, `technical reasons' :-)). The code which
	actually makes things faster was contributed to zgv by Costa
	Sapuntzakis.

1999-10-24  Russell Marks  <rus@cartman>

	* doc/xzgv.texi: hacked to reflect recent changes.

	* src/main.c: you can now `close' a file (clear the viewer,
	returning to the startup logo).

	* src/gotodir.c: `go to dir' dialog. (Only text-entry for now (!),
	but I'll probably extend it at some point.) Changed Sort Order
	menu items to be `Sort by Name' etc. under new `Directory' menu to
	accomodate this as Directory/Change (also on G (zgv-like)). Added
	Directory/Rescan (^R) while I was at it. :-)

	* src/main.c: error dialog looked weird before, doesn't look as
	weird now. :-)

1999-10-23  Russell Marks  <rus@cartman>

	* src/main.c: Esc now exits an error dialog (making it consistent
	with the other ones).

	* src/filedetails.c: `file details' dialog - selected by
	File/Details or (as in zgv) `:'/`;'. Includes width/height from
	thumbnail, if present. (Thumbnails from versions of zgv before 5.0
	didn't include this - you may to delete your old thumbnails and
	`update' if you find that a problem. Note that thumbnails
	generated with xzgv/xv/Gimp should be ok.)

	* src/main.c: right-clicking on the selector to get the menu
	now also moves the focus row (keyboard cursor) to the file you
	right-clicked on (and switches focus to the selector). This
	should give us a way of doing single-file operations (well,
	those other than viewing) with the mouse, without needing to
	sacrifice the IMHO very nice single-click-to-view behaviour.

1999-10-20  Russell Marks  <rus@cartman>

	* Replaced the directory/file-without-thumbnail icons with nicer
	ones. They're loosely based on gmc's `dir-close.xpm', which I
	think Tuomas Kuosmanen was responsible for (judging from the
	change log). Thanks also to Steven Flintham for pointing out that
	the old icons were pretty crap. :-)

1999-10-19  Russell Marks  <rus@cartman>

	* Bothered giving it a half-decent logo. :-) Also has a similar
	icon.

	* src/main.c: thumbnail updates now make sure any row a thumbnail
	is being updated for is visible, making the update look more like
	it does in zgv - as well as making it rather more clear what's
	going on. :-) (The old position is restored when the update is
	finished.)

1999-10-03  Russell Marks  <rus@cartman>

	* src/main.c: made middle-click on the viewer toggle the selector
	rather than always acting like Exit viewer. Thanks to Steven
	Flintham for suggesting this.

	* src/main.c: previously segfaulted on files less than 4 bytes
	long due to a typo. Um, whoops... :-}

1999-09-30  Russell Marks  <rus@cartman>

	* src/readgif.c: shouldn't hang on some corrupt GIFs now. This
	change reflects the one in zgv 5.0, and thanks go to Andy Mortimer
	for the fix (to zgv, but it (currently) applies to xzgv too).

1999-09-27  Russell Marks  <rus@cartman>

	* doc/xzgv.texi: corrected a couple of typos.

1999-09-14  Russell Marks  <rus@cartman>

	* src/main.c: now has tagging - `-' untags, `=' tags, and with
	Alt (Meta) they untag/tag all. As for the mouse, ctrl-click
	tags/untags, and there's now a File menu (might become Tagging
	or similar, haven't really made up my mind) which has items
	for tag/untag all. No way of tagging from the viewer
	currently, though, and at the moment nothing at all takes any
	notice of whether a file is tagged or not. :-) (Also, you
	can't tell if a file is tagged if it's also selected!)

1999-09-12  Russell Marks  <rus@cartman>

	* src/main.c: pixmaps for dirs and thumbnailless pics are now
	shaped, rather than having an ugly white background.

	* src/main.c: another focus-row bug fixed - when the selector lost
	focus due to selecting a picture, it didn't undraw the focused
	row. (This isn't very obvious with the default GTK+ theme, but it
	really shows up with e.g. Rasterman's `pixmap' one.) This was due
	to my disabling can-focus *before* changing focus (whoops).

	* src/main.c: fixed problem where xzgv's moving the focused row
	`by hand' sometimes messed up the display.

1999-09-08  Russell Marks  <rus@cartman>

	* doc/makeman.awk: previously the last output line of a
	paragraph was never escaped, meaning it would most likely be
	lost if it began with a dot (this mangled the first paragraph
	of the `Updating Thumbnails' node).

1999-09-02  Russell Marks  <rus@cartman>

	* doc/xzgv.texi (Updating Thumbnails): fixed fixed double double
	word word. :-)

	* Version 0.1.

	* doc/xzgv.texi: cleaned up - mainly a matter of updating a few
	bits, and removing all the zgv stuff which doesn't yet apply (for
	as-yet-unimplemented stuff like brightness/contrast, tagging,
	slideshows... the list goes on :-)).

	* Various cmdline/config options added, so that all runtime
	options can now have defaults messed about with. :-)

	* src/main.c: previously render_pixmap() didn't bother checking if
	theimage was NULL (i.e. if no picture was loaded), which broke
	e.g. `xzgv --zoom *.jpg'.

	* Rearranged things to give a more zgv-like directory layout,
	things were getting a bit confusing with all sorts packed into one
	dir.

	* rcfile.c: ok, it was deeply hairy, but I've converted zgv's
	option-parsing and config-file-reading code and (the hairy part)
	added long-option support, making long-option names and config
	file variable names the same, and having stuff only defined once.
	I thought I'd be able to use some cpp trickery to get this
	working, but I ended up using an awk script. :-/

	* main.c: finally have keyboard control over relative window sizes
	(paned widget). `[' moves splitter left, `]' moves it right,
	with ctrl+[ and ctrl+] moving in smaller steps. `~' returns
	selector to default size, as well as unhiding it.

	* main.c: cursor-key equivalents of the small hjkl movements
	added; ctrl-cursor moves 10 rather than 100 pixels.

	* main.c: fixed bug where any viewer exposure after a
	failed-picture-load caused a segfault. (!) I think the code
	changes I needed for scaling probably teased this one out, as that
	works with the imlib image itself, rather than a pixmap rendered
	by it.

1999-08-05  Russell Marks  <rus@cartman>

	* doc/xzgv.texi: created, based on zgv's zgv.texi. Pretty scrappy
	for now, but at least I've started. :-)

1999-08-04  Russell Marks  <rus@cartman>

	* main.c: thumbnail column now matches maximum possible thumbnail
	width, making thin rows mode look a *lot* better.

	* main.c: menus popped up with F10 now appear in more reasonable
	places (top-left of the subwindow they were popped up from).

	* main.c: you can now iconify (minimise) the window with ^Z. I
	also put it on the menu, which might be handy if you're running
	fullscreen and don't know what a keyboard is. :-) Also moved `hide
	selector' to the new `window' menu created primarily for minimise.

	* main.c: rearranged some menu items - in particular, shifted all
	viewer toggles onto an `options' menu. It looked ugly with the
	options littering otherwise `normal' menus, and I'm not sure that
	(e.g.) having zoom on the scaling menu was all that smart to begin
	with. :-)

	* main.c: fullscreen option (start with `-f'). Uses the entire
	screen with no window frame or anything (if your wm recognises the
	decor hints - I think they're mwm ones, but fvwm handles them,
	meaning that most wm's around today do :-)). I tried having it as
	a run-time option, but it was just too evil trying to `switch
	back' from fullscreen, and I never got it entirely working.

1999-08-02  Russell Marks  <rus@cartman>

	* main.c: now has the full range of revert stuff from zgv. This
	has been streamlined a little to make sense in the largely
	modeless xzgv, so now you only have the revert-orientation option,
	but it's on the viewer menu so the effect of zgv's
	saved-orientation stuff isn't too hard to duplicate.

	* main.c: now supports scaling, interpolation and all. :-) Since
	keeping a scaled-up image in memory would take up a LOT of room
	(we're talking hundreds of megs, even gigs - work it out), the
	scaling has to be done on the fly, so it's a bit slow even on
	(what I would consider to be) a fast machine. But hey, at least
	it's there, and nothing's any slower when you're not using it.

	* main.c: thumbnail update now updates pixmaps in selector
	directly. This is more efficient than the old behaviour, and has
	the additional advantage that you can get to see thumbnails even
	if you don't have permission to write them (though you'd have to
	do an update every time you revisited the dir!).

	* main.c: couldn't-load-file errors now go in dialog rather than
	on stderr. :-) They also result in the selector being shown,
	useful if you ran xzgv on pics from the command-line.

1999-08-01  Russell Marks  <rus@cartman>

	* main.c: made thin rows mode considerably more useful by
	maintaining a separate rescaled thumbnail. This is only rescaled
	crudely (a take-every-nth-pixel approach), but it works
	surprisingly well.

1999-07-31  Russell Marks  <rus@cartman>

	* main.c: selector now has zgv-like goto-next-char on g and '.
	Like in zgv, there's no indication that it's waiting for a char,
	so I've made it timeout after two seconds in case of accidental
	presses and the like. (Strictly speaking it doesn't *wait* for the
	char; the initial g or ' just sets a flag.)

	* main.c: F10 now pops up the right-button menu (in both the
	selector and the viewer). You can now also use Enter (well,
	actually Return) instead of Space as an alternative way of
	selecting a pic.

	* main.c: markedly improved keyboard support in viewer by handling
	keypresses directly. This is a bit kludgey really, but given that
	keyboard movement is now quite faithfully zgv-like, I think it's
	worth it. :-) Had to move hide-selector to shift-z (the idea being
	it's a bit like zoom but in a different sense) to make room for
	hjkl; while I was at it, I changed hide to really be a hide/unhide
	toggle.

1999-07-28  Russell Marks  <rus@cartman>

	* main.c: bugfix after trying it on my 486 - it wasn't giving GTK+
	a chance to run after creating the `Updating Thumbnails' window
	until after the first file's thumbnail had been checked/updated,
	leaving the window briefly blank. (Since the first file is almost
	always `..', it takes very little time to deal with (as dirs don't
	have thumbnails), so much so that I hadn't noticed this delay at
	all on cartman.)

1999-07-27  Russell Marks  <rus@cartman>

	* main.c: now supports loading picture(s) from command-line. Works
	by faking up a selector `directory' containing them, and hiding
	the selector.

	* main.c: can now explicitly hide selector from viewer. Probably
	more useful than auto-hide mode for most people, I'd have thought;
	you might find having the selector visible fine generally, but
	still occasionally need the full window for a big image.

	* main.c: finally, has create/update thumbnails. Also added
	`pastpos' stuff from zgv, which remembers where you were when you
	last left a previously-visited directory.

	* main.c: viewer now uses pixmap background. This causes some
	difficulties (which I've mostly managed to work around - er, I
	hope :-)), but makes scrolling much easier on the eye. Also
	disabled "Reading thumbnails" messages by default and added option
	to enable them.

1999-07-25  Russell Marks  <rus@cartman>

	* main.c: middle button now does `exit viewer', like Esc (and
	equivalent menu option). Handy when in auto-hide mode.

	* main.c: added auto-hide mode. Rather nice for those of us
	running in relatively low resolutions. :-) However, since I reckon
	you're unlikely to want it if you're running in 800x600 or
	greater, and since it can be a little confusing, I've resisted the
	temptation to make it the default.

1999-07-24  Russell Marks  <rus@cartman>

	* main.c: cleaned up some early kludgey stuff - in particular,
	removed the long-gone quit button (which until now was merely not
	shown, ouch :-)). It's still fairly kludgey in parts, but one
	thing at a time eh...

	* main.c: fixed `losing' of current selection and focus row
	(the keyboard cursor) when sort order is changed. Also fixed
	the focus to match selection in this case, and in the other
	cases where it was previously a problem (next/prev image, and
	thin rows toggle).

1999-07-23  Russell Marks  <rus@cartman>

	* Kludged around apparently-buggy imlib GIF support (in v1.9.5 at
	least) by adding my own GIF support, via readgif.c and wrapper
	mentioned below. Hopefully this will only be a temporary kludge
	until imlib gets fixed. :-) PNGs with few colours also have
	problems, but that's not so easy to work around, unfortunately.
	(Rather, it is in theory, but PNG is a much harder format to read;
	readgif.c is only about 400 lines.)

	* main.c: now has next/previous image in viewer (on space and b
	rather than zgv's space and del, as a) del/backspace issues are
	non-trivial in X and b) I couldn't get del to work :-)).

	* Added mrf support via readmrf.c and wrapper for
	gdk_imlib_load_image(). This is probably the only way mrf support
	would get added, as imlib only seems to support the most popular
	formats `natively'.

	* main.c: finally you can change dir once it's started. :-) Also
	added custom sorting routine (so dirs come first, thank ghod for
	that), and different sorting orders (as in zgv).

	* main.c: loads of changes. Fixed memory leak the size of a planet
	(50 meg X server, anyone? :-)), made image draggable with the
	mouse, added right-button menus for both selector and viewer,
	added `thin rows', `status bar' and `zoom' options, and probably
	lots more I can't remember right now.

1999-07-22  Russell Marks  <rus@cartman>

	* First, really crap version. (Several more really crap versions
	to follow. :-))
