	Use minimal fallback resources in favour of an application defaults
	file.

2001-10-25  adoline  <adoline@dugong>

	* AUTHORS: Updated email address.

2001-10-25  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c:
	Look for elements file in: XM_ELEMENTS (file or directory), ELEMENTS
	(compiled in location), and the current working directory.

	* gl_funcs.c:
	Moved referenced to display_env inside SGI_STEREO conditional.

	* AUTHORS, INSTALL, Makefile.am, NEWS, README, acconfig.h, acinclude.m4, animate.c, bbox.c, canvas.c, config.h, configure.in, control.c, draw.c, edit.c, file.c, frames.c, gl_funcs.c, globals.h, help.c, menus.c, region.c, rotate.c, sort.c, store.c, track.c, translate.c, utils.c, vectors.c, view.c, xmakemol.c:
	XMakemol now officially has autoconf support. [Toni Ronkko] Other
	associated changes, including those contributed for the FreeBSD port.
	[Chi Zhang]

2001-10-23  adoline  <adoline@dugong>

	* file.c:
	Fixed bug caused by rearranging widgets in gl_render_dialog.  If the dialog had
	been opened, and then a file was loaded, the eye_scale widget would be
	referenced through the hierachical names of its parent widgets up to
	gl_render_dialog, and this led to setting the value of the widget using a null
	reference because the hierarchy was no longer correct.

	* gl_funcs.c:
	Don't allow change to SGI stereo mode if running on a remote display, since the local display would still change to the STR_TOP resolution and refresh rate.

2001-10-15  Matt Hodges  <MPHodges@member.fsf.org>

	* Makefile.orig: Updated the dependencies; tidied things up.

	* rescale.c: Obsolete.

	* Makefile:
	Makefile should be generated from Makefile.orig and edited. Hence, I
	don't want this in the repository.

	* Makefile.orig, animate.c, basename.c, file.c, frames.c:
	Use basename () from the GNU C library.

2001-10-12  adoline  <adoline@dugong>

	* edit.c, gl_funcs.c:
	Only change to hardware stereo mode on SGI's when gl rendering is enabled
	and SGI Stereo radio button is selected.

	* edit.c:
	Changed layout of widgets in GL dialog such that all the widgets will be
	visible when in SGI Stereo mode.

2001-10-04  adoline  <adoline@dugong>

	* gl_funcs.c:
	When switching to stereo mode on SGI, height is set to 392; anything larger
	than this will hide the status bar. (Not sure if 392 is appropiate for
	all SGI's... tested on an O2 so far)

2001-10-03  adoline  <adoline@dugong>

	* gl_funcs.c: Corrected error message concerning SGI stereo support

	* control.c, edit.c, file.c, gl_funcs.c, track.c:
	Changed typecasts from (int) to appropriate (enum ___) typecasts to eliminate
	some warnings when compiling with cc

2001-10-02  adoline  <adoline@dugong>

	* file.c, gl_funcs.c:
	Added code to update gl_eye upon reading a file such that the initial
	rendering of the image in GL looks similar to the initial rendering in X11.

2001-09-28  Matt Hodges  <MPHodges@member.fsf.org>

	* canvas.c: Corrected conditional compilation error.

2001-09-25  Matt Hodges  <MPHodges@member.fsf.org>

	* animate.c, file.c, frames.c:
	Fixed problems with writing XPM files due to missing colormap in a
	call to XpmWriteFileFromPixmap. (Affected machines with multiple
	visuals of different kinds simultaneously on screen.) [Toni Ronkko]

2001-09-24  adoline  <adoline@dugong>

	* gl_funcs.c, xmakemol.c:
	Toni Ronkko's patch for keeping molecule centered maintains the image's
	aspect ratio after resizing, so I'm using a new method to scale the image
	extra wide for SGI stereo mode.  Now simply calling glScalef with modified
	x arg.
	Also removed some code made redundant by the patch from canvas_resize_cb.

	* Makefile, file.c, xmakemol.c:
	I messed up the log entry on my last revision of these files.  The update
	text was supposed to be this:
	Added cleanup_cb function to do any cleanup before program exits. Currently
	using this to change from stereo resolution on SGI back to normal resolution.
	cleanup_cb called if user selects 'quit' from File menu, or selects 'close'
	option from window manager titlebar button.

	* Makefile, file.c, gl_funcs.c, xmakemol.c: /tmp/cvsqmWfPM

2001-09-24  Matt Hodges  <MPHodges@member.fsf.org>

	* canvas.c, file.c, gl_funcs.c, globals.h, xmakemol.c:
	Applied patch from Toni Ronkko to keep the molecule centered when
	resizing the main window.

2001-09-21  adoline  <adoline@dugong>

	* gl_funcs.c:
	Removed the global boolean variable displaying_stereo, using
	XSGIQueryStereoMode to determine if we're displaying stereo instead.

	* Makefile, Makefile.orig:
	Changed some of text regarding stereo stuff in Makefile and Makefile.orig,
	added dependency on utils.c for gl_funcs.o

2001-09-21  Matt Hodges  <MPHodges@member.fsf.org>

	* xmakemol.1: Fixed typo.

2001-09-20  adoline  <adoline@dugong>

	* bbox.c, canvas.c, file.c:
	Fixed memory leak caused by repeated calls to XCreateColormap in
	canvas_cb(), draw_bbox_face(), and frame_content_to_atoms() when GL is defined.
	Added appropiate calls to XFreeColormap() to free memory.  May be better to
	create global cmap variable once instead of repeatedly creating and deleteing
	colormaps...

	* Makefile:
	Previously comitted my working Makefile instead of copy of Makefile.orig.
	Correcting Makefile back to unaltered copy of Makefile.orig.

	* Makefile, edit.c, gl_funcs.c:
	Added #ifdef SGI_STEREO ... #endif statements so Crystaleyes options only show
	up when CE_DEFS and CE_LIBS are defined in the Makefile.  These defines should
	only work on SGI machines, other platforms will complain about missing include
	files, etc.

2001-09-20  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c:
	If XM_ELEMENTS is a directory, append `/elements' and try to open that
	file before falling back on the default.

	* xmakemol.c: Changed the application class to XMakemol.

2001-09-19  adoline  <adoline@dugong>

	* Makefile, Makefile.orig, edit.c, gl_funcs.c:
	Added CE_DEFS and CE_LIBS for CrystalEyes support in Makefile.orig.
	Using SGI system calls to check for stereo support instead of assuming
	it exists.

	* Makefile, edit.c, gl_funcs.c, globals.h, utils.c, xmakemol.c:
	Support for Crystaleyes stereographic glasses on SGI machines.  Requires
	SGI_STEREO to be defined at in Makefile.

2001-08-22  Matt Hodges  <MPHodges@member.fsf.org>

	* xmakemol.1: Fix -h switch description.

	* Makefile.orig: Change location of binary installation.

	* Makefile.orig: Added install rule for manpage.

	* Makefile.orig: Distribute the manpage.

	* xmakemol.1: Initial draft.

	* ToDo.txt: Updated.

	* Makefile.orig: Added Xext, pthread and dl libraries to link.

	* VERSION: Version 4.41 released.

	* canvas.c, draw.c, file.c, gl_funcs.c, globals.h, rotate.c, vectors.c:
	Added capability to have more than one vector per atom; the relevant
	parameter is set to three by default.

2001-05-15  Matt Hodges  <MPHodges@member.fsf.org>

	* help.c: Allocate sufficient memory for about_string.

2001-05-08  Matt Hodges  <MPHodges@member.fsf.org>

	* VERSION: Version 4.40 released.

2001-04-26  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c:
	Set current_file_name when reading from STDIN so that translations
	don't get ignored in track ().

2001-04-25  Matt Hodges  <MPHodges@member.fsf.org>

	* edit.c, gl_funcs.c:
	Added specular lighting configuration for GL rendering.

	* xmakemol.c:
	Added -G option to start with GL rendering if GL support enabled.

2001-04-24  Matt Hodges  <MPHodges@member.fsf.org>

	* Makefile.orig, bbox.c, canvas.c, file.c, xmakemol.c:
	Fix compilation problems when -DGL is not specified.

2001-04-17  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c: Fixed checking of optional input strings.

	* file.c:
	Make sure vector/ellipse properties are initialized for atoms which
	don't have them.

2001-04-17  adoline  <adoline@dugong>

	* globals.h, xmakemol.c, Makefile, Makefile.orig, bbox.c, canvas.c, file.c, gl_funcs.c:
	Removed need to disable x-rendering on SGI machines.  Edited calls to
	XCreateGC, XCopyArea, XCreatePixmapFromData, XCreateColormap to reference
	canvas instead of root_window, and visinfo visual instead of default visual.

2001-04-17  Matt Hodges  <MPHodges@member.fsf.org>

	* gl_funcs.c:
	Render ellipses in TUBES mode iff the atom is not bonded to anything
	else.

	* control.c, globals.h: Removed global scale variable.

	* file.c: Keep track of the maximum elliptical scaling parameter.

	* utils.c: Fixed Euler angle matrix.

	* gl_funcs.c:
	Don't render ellipses when not in BALL_AND_STICK mode; minor fix in
	gl_open_file_init.

	* gl_funcs.c:
	Take into account elliptical units when updating near/far GL clipping.

	* gl_funcs.c:
	Only apply the vector-clipping fudge if vectors are being rendered.

	* Makefile, Makefile.orig, canvas.c, defs.h, draw.h, edit.c, file.c, frames.c, gl_funcs.c, globals.h, rotate.c, utils.c:
	Added basic support for specifying elliptical units; vectors are now
	specified on a per-atom basis; clipping of vectors (GL) is now
	implemented (including one fudge factor).

2001-03-22  Matt Hodges  <MPHodges@member.fsf.org>

	* edit.c:
	Use get_no_elements when making Widgets in make_edit_visi_dialog.

2001-03-21  Matt Hodges  <MPHodges@member.fsf.org>

	* gl_funcs.c: Changed vector colour to shade of grey.

	* edit.c:
	Use get_no_elements when making Widgets in make_edit_posn_dialog.

2001-03-20  adoline  <adoline@dugong>

	* edit.c:
	Commented out XtSetSensitive code to avoid problems with HP/UX.

2001-03-02  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c: Include <alloca.h> (hopefully no platform dependence).

2001-03-01  adoline  <adoline@dugong>

	* xmakemol.c:
	Fixed the segmentation faults when using the custom translation table
	with the Glw and GlwM drawing area widgets, for real this time!  Problem was
	in the ManagerGadget* function calls in the translation table.  They seem
	to be specific to the Motif DrawingArea widget, and they were causing the
	crashes in the GLw and GLwM widgets.

2001-02-28  Matt Hodges  <MPHodges@member.fsf.org>

	* frames.c: Removed comment.

	* frames.c, utils.c:
	New function clear_message_area (better implemetation?). Display frame
	label if the frame is changed and frames_dialog is not mapped.

2001-02-27  adoline  <adoline@dugong>

	* xmakemol.c:
	Changed from using GLwM widget for canvas to GLw widget when SGI_GL is
	defined.  GLwM causes crashes for an unknown reason, but using the GLw
	widget instead seems to resolve this problem.

	* canvas.c, gl_funcs.c:
	Moved code to initialize background color from x_render function to
	bg_color_init in canvas.c.  This allows us to initialize the
	background color even if we are disabling x-rendering, and thus not
	entering the x_render function.  If SGI_GL is defined, bg_color_init
	is called in gl_init.

	* file.c:
	Added a typecast from char to int for isalnum function so compiler won't
	give us a warning.

2001-02-21  Matt Hodges  <MPHodges@member.fsf.org>

	* xmakemol.c: Added missing terminators in translations.

2001-02-20  adoline  <adoline@dugong>

	* Makefile:
	Same update as for Makefile.orig: Added option to GL_DEFS so user may
	define SGL_GL in case they are having trouble getting it to work on an
	SGI machine.

	* Makefile.orig:
	Added option to GL_DEFS so user can define SGI_GL in case they are having
	trouble getting GL to work.  Defining SGI_GL disables X rendering.

	* Makefile, animate.c, canvas.c, draw.c, edit.c, file.c, gl_funcs.c, globals.h, xmakemol.c:
	Added stereo functionality to opengl mode, works with red-blue stereo
	glasses.  Enabled by option button in edit->gl rendering.  Seperation
	of left and right fields can be controlled with slider bar in dialog.

	Added code to set gl_eye automatically for each file when loaded, so
	that initial scaling between x rendering and gl rendering is nearly
	the same.

	Numerous other small bits of cleaning up code.

2001-01-23  adoline  <adoline@dugong>

	* track.c:
	Don't do translations if we haven't loaded a file yet, as clicking the mouse
	around the initial screen can cause a divide by zero error.

2000-11-08  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c, xmakemol.c:
	Change the locale for category LC_NUMERIC to "C" after the application
	has been initialized. If a parse error occurs when reading an XYZ
	file, print LC_NUMERIC to stderr.

2000-10-27  Matt Hodges  <MPHodges@member.fsf.org>

	* edit.c, gl_funcs.c:
	Add option to toggle use of lighting (on by default).

2000-10-26  Matt Hodges  <MPHodges@member.fsf.org>

	* control.c: Fixed sign of torsion angle (I hope).

2000-10-25  Matt Hodges  <MPHodges@member.fsf.org>

	* gl_funcs.c:
	Made outline mode much more efficient when using GL by disabling some
	unnecessary features: lighting, depth and colour.

2000-10-18  Matt Hodges  <MPHodges@member.fsf.org>

	* VERSION: Version 4.30 released.

	* Makefile.orig: Brought into line with Makefile.

2000-10-17  adoline  <adoline@dugong>

	* file.c:
	Removed debugging line from print_file_cb that sends the print command to
	stderr.

2000-10-17  Matt Hodges  <MPHodges@member.fsf.org>

	* XMakemol.ad: Much simplified version.

	* animate.c, canvas.c, control.c, edit.c, file.c, frames.c, track.c, xmakemol.c:
	Untabified source.

	* file.c:
	Use mkstemp rather than mktemp in print_file_cb. write_eps () now
	takes an additional argument (type FILE *), which if non-NULL is used
	rather than opening the file given by file_name.

	* Makefile: Produce gzipped tar file in current directory.

2000-10-04  Matt Hodges  <MPHodges@member.fsf.org>

	* gl_funcs.c:
	Fixed some rendering details. In TUBES rendering mode, atoms and bonds
	are treated as mutually exclusive. An atom in a bond will only be
	displayed if bonds are being displayed and is not affected by whether
	or not atoms are being displayed. Fixed the rendering of H-bonds for
	all the combinations.

	* draw.c:
	Fixed rendering of H-bonds to atoms which aren't themselves bonded.

2000-10-02  Matt Hodges  <MPHodges@member.fsf.org>

	* gl_funcs.c, utils.c:
	Optimizations: unrolled some functions in utils.c; reorganized use of
	quadrics in gl_funcs.c (use one for all rendering).

	* canvas.c, edit.c, gl_funcs.c, gl_funcs.h, xmakemol.c:
	Rendering with GL now happens directly onto XtWindow (canvas) as
	working with a pixmap caused problems that I couldn't resolve on some
	displays. This means that the contents of the window have to be copied
	to canvas_pm for outputting in XPM format (though this should be made
	conditional for performance benefits).

2000-10-02  adoline  <adoline@dugong>

	* edit.c, file.c:
	edit.c: removed global variable related to set background color dialog.
	file.c: fixed seg fault that occured when /etc/printcap does not exist, and
	user tries to open print dialog.

2000-09-29  adoline  <adoline@dugong>

	* edit.c, menus.c:
	Commented out code for set background color dialog and removed option from edit menu.  May possibly reuse code for dialog later if a preferences dialog is added, along with facility to save preferences.

2000-09-29  Matt Hodges  <MPHodges@member.fsf.org>

	* gl_funcs.c:
	Call gl_set_perspective whenever the scene changes. Updated values of
	near and far based on the current positions of the atoms are
	calculated in gl_update_near_and_far. The calculation of the near
	point takes into account the van der Waals radius (unscaled) and the
	far point adds a bit of leeway for correct rendering of the furthest
	disk in outline mode.

	* gl_funcs.c: Added outline capabilities for GL rendering.

2000-09-28  Matt Hodges  <MPHodges@member.fsf.org>

	* canvas.c, draw.c, globals.h, view.c:
	Replaced update_efficiently with outline_mode, accessible with
	outline_mode_p ().

2000-09-26  adoline  <adoline@dugong>

	* AUTHORS: Added my name and email to AUTHORS

	* canvas.c, draw.c, edit.c, file.c, globals.h, menus.c, xmakemol.c:
	Merged all the changes I've made locally since beginning work on xmakemol
	in June of 2000.  All sections I changed or modified are marked with my
	initals: "aro".

2000-09-25  Matt Hodges  <MPHodges@member.fsf.org>

	* track.c:
	Cosmetic changes plus useful comment to remind me about mouse_motion.

	* canvas.c, draw.c, file.c, globals.h, help.c, menus.c, region.c, rotate.c, track.c, xmakemol.c:
	Changed the mouse translations (code should be more easily
	maintainable now); see Help->Mouse for the new bindings.

2000-09-19  Matt Hodges  <MPHodges@member.fsf.org>

	* xm_logo_1.h: No longer needed in distribution.

	* file.c, globals.h, canvas.c:
	More flexibility for merging files; either the first frame can be
	mapped onto all frames or frames can be mapped on a one to one basis.
	Note that in the latter case, merging stops if an EOF is detected in
	the file to be merged (ie the original frame contents are preserved
	for subsequent frames).

	Defined (and used) new global variable, inhibit_canvas_callback, which
	prevents any redisplays if canvas_cb is called.

	* VERSION: File to store XMakemol version.

2000-09-18  Matt Hodges  <MPHodges@member.fsf.org>

	* AUTHORS: Added me and blank contributions.

2000-07-21  Matt Hodges  <MPHodges@member.fsf.org>

	* xmakemol.c:
	Set xmakemol_version at the beginning of main (before get_options is
	called); xmakemol -v will correctly print the version now.

	* Makefile, Makefile.orig: Added install: target.

2000-06-21  Matt Hodges  <MPHodges@member.fsf.org>

	* Makefile, Makefile.orig:
	Get version from file VERSION, which is now included with the
	distribution.

	Render using van der Waals radii for atoms which are not bonded to
	anything else.

	* edit.c, gl_funcs.c, gl_funcs.h:
	Defined GL rendering modes BALL_AND_STICK and TUBES.

2000-06-07  Matt Hodges  <MPHodges@member.fsf.org>

	* Makefile.orig, Makefile:
	Include AUTHORS file in the distribution; this should be an obvious
	place to look for an e-mail address for bug reports etc.

	Changed abs () to fabs () to avoid problems on alpha architectures.

	* control.c, file.c:
	Changed log (2) to log (2.0) to avoid problems on alpha architectures.

	* gl_funcs.c: First attempt at stippling selected atoms.

2000-05-05  Matt Hodges  <MPHodges@member.fsf.org>

	* gl_funcs.c:

	Added more GL rendering control; details of atoms/bonds/hbonds.

	* file.c: Print any line not parsed to stderr.

	* PROBLEMS: Added note about LANG problems.

	* PROBLEMS: New file.

2000-05-04  Matt Hodges  <MPHodges@member.fsf.org>

	* xmake_anim.pl: More robust sorting of frame numbers.

2000-04-27  Matt Hodges  <MPHodges@member.fsf.org>

	* animate.c:
	Don't update message area during animation more often than once every
	0.5 seconds.

2000-04-05  Matt Hodges  <MPHodges@member.fsf.org>

	* gl_funcs.c, vectors.h: Updated Copyright information.

	* xmake_anim.pl: Use ImageMagick `convert' program if available.

	* control.c: Fixed bug associated with dead widget.

	* file.c: Don't spit out warning if aux file doesn't exist.

	* control.c, file.c, globals.h, help.c, xmakemol.c, Makefile, Makefile.orig, canvas.c, edit.c, frames.c, menus.c:
	Updated Copyright years.

1998-10-27  Matt Hodges  <MPHodges@member.fsf.org>

	* globals.h: Standardized and protected against multiple inclusion.

	* globals.h: Factored out structs (atoms, elements, frames).

	* globals.h, xmakemol.c: Cosmetic change of MAIN to __XMAKEMOL_C__.

	* bonds.h: Factored out struct node.

	* Makefile, Makefile.orig, menus.c, xmakemol.c, file.c, bbox.c, canvas.c, draw.c, globals.h, view.c:
	Use view.h.

	* view.h: New file.

	* globals.h:
	Removed vectors_flag and vectors_are_available: vectors may one day be
	available.

	* globals.h:
	Removed all entries to the unused dist_flag variable. Where _do_ these
	things come from?

	* Makefile, Makefile.orig, bbox.c, globals.h: Use bbox.h.

	* bbox.h: New file.

	* edit.c, file.c, globals.h:
	Removed all entries to the unused max_bond_sep2 variable. Where _do_
	these things come from?

	* bonds.h, file.c: Cosmetic change of FILE_C to __FILE_C__.

	* globals.h: Removed spurious bond_len and bond_len2 variables.

	* bonds.h: Cosmetic change of BONDS_H to __BONDS_H__.

	* edit.c, rotate.c, globals.h:
	Changed integer variable global to rotate_about_global, which seems a
	little more specific.

1998-10-26  Matt Hodges  <MPHodges@member.fsf.org>

	* elements: Added entry for GE (parameters from rdo).

1998-10-07  Matt Hodges  <MPHodges@member.fsf.org>

	* Makefile, Makefile.orig, README: Version 4.09 released.

	* control.c: Sign of torsion is now defined.

1998-10-06  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c:
	No type was specified for no_elements - it should have been int.

	* frames.c:
	We shouldn't have to prototype usleep - put up with any compiler warnings.

1998-10-02  Matt Hodges  <MPHodges@member.fsf.org>

	* INSTALL: Linux support.

	* Makefile, Makefile.orig, README: Version 4.08 released.

	* file.c: Incorrect parameter definition for free_bond_adjacency_list.

	* Makefile, Makefile.orig: Cosmetic change.

	* frames.c:
	Added prototype for usleep - hopefully correct for all setups.

	* Makefile, Makefile.orig: Cosmetic changes.

	* Makefile, Makefile.orig: Added Linux support to Makefile.

	* Makefile.orig, Makefile: Unwrapped line.

	* Makefile, Makefile.orig: Expunged DEFS.

	* animate.c, file.c: Added <libgen.h>.

	* frames.c:
	Now uniformly using usleep, as this seems to be standard across the
	platforms.

	* animate.c, file.c:
	libgen.h seems to be available on DECs now - in libc, so no -lgen
	needed in LIBS.

1998-10-01  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c: Removed convolution of calls to free_bond_adjacency_list().

	* file.c:
	Made free_bond_adjacency_list a parameterless function - keep track of
	the allocation of bond_adjacency_list and hbond_adjacency_list at
	mallocation time (bond_adjacency_lists_allocated_size).

1998-09-30  Matt Hodges  <MPHodges@member.fsf.org>

	* Makefile, Makefile.orig, README: Version 4.07 released.

	* xmakemol.c: Removed extraneous variable.

	* file.c: Free H-bond list as well - fixes memory leak presumably.

	* file.c: Removed buggy free() line.

1998-09-29  Matt Hodges  <MPHodges@member.fsf.org>

	* README, Makefile, Makefile.orig: Version 4.06 released.

	* file.c: Added option to save XYZ frame with connectivity information.

1998-09-23  Matt Hodges  <MPHodges@member.fsf.org>

	* globals.h: Removed erroneous variable pixmap_index.

1998-09-17  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c: Made *.xyz the default pattern (filter) for opening a file.

1998-08-20  Matt Hodges  <MPHodges@member.fsf.org>

	* Makefile, Makefile.orig, README: Version 4.05 released.

	* edit.c: Changed widget labels, for clarity.

	* edit.c, file.c:
	The "Edit visible atoms" and "Edit relative positions" dialogs now
	retain their positions when a new file is loaded. Unfortunately,
	unmanaging the widgets doesn't work very well when combined with
	dynamically allocating the sub-widgets, so they have to be destroyed.

	Unfortunately, when destroyed and resurrected any positioning
	information is ignored, and the widgets have to moved after they have
	been managed. This is not ideal, and causes a small amount of flicker,
	but overall this is my preferred solution to the problem and is better
	than the dialogs going back to their original positions, which usually
	means obscuring the main window.

1998-08-17  Matt Hodges  <MPHodges@member.fsf.org>

	* xm_logo_1.h:
	Colour of background now consistent with default background colour of
	the canvas.

1998-08-13  Matt Hodges  <MPHodges@member.fsf.org>

	* README, Makefile, Makefile.orig: Version 4.04 released.

	* file.c, control.c, frames.c, edit.c:
	Made a whole series of changes which stop the simple dialog being
	popped down and back up when a new file is loaded. The only ones not
	changed are the "Edit visible atoms" and "Edit relative positions" as
	they have dynamic widgets. Maybe this won't be too hard to fix though.

1998-08-11  Matt Hodges  <MPHodges@member.fsf.org>

	* XMakemol.ad: Added legal headers.

	* INSTALL: Added entry about the application defaults file.

	* Makefile, Makefile.orig:
	Added "Configure" line. Didn't this used to be here?

	* help.c: Fixed bug which allowed all the help messages to be multiply
	displayed. Made the strings use allocated memory.

	* README, Makefile, Makefile.orig: Version 4.03 released.

	* track.c, control.c:
	The measure dialog now uses a fixed-width font, and the formats have
	been updated to reflect this.

	* control.c: Removed spurious MEAS_WIDTH, whatever that was.

	* Makefile.orig, Makefile: Added XMakemol.ad to TAR.

	* XMakemol.ad: New file.

1998-07-30  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c: Changed some printf's to fprintf's.

	* globals.h: Tidied up some stuff.

	* file.c: Removed spurious print statement.

	* globals.h, file.c, edit.c:
	The internal comparison of atom labels and element names is now always
	with uppercased variants. atoms[i].uppercase_label is now used.

	* edit.c:
	In posn_atoms_type_cb, made the comparison for atom_type with an
	uppercased label. This was already the case for toggling visibility,
	but had been overlooked here.

	* file.c:
	Changed the way the elements are allocated. The code now checks that
	the number of elements in the file is not exceeding the parameter
	MAX_ELEMENTS.

1998-07-29  Matt Hodges  <MPHodges@member.fsf.org>

	* xm_logo_1.h: New file.

	* track.c: static closest was not typed explicitly.

1998-07-28  Matt Hodges  <MPHodges@member.fsf.org>

	* README, Makefile, Makefile.orig: Version 4.02 released.

	* track.c:
	We need to call count_visible_atoms in select_atom_dialog as the
	number changes.

	* README, Makefile, Makefile.orig: Version 4.01 released.

	* xmakemol.c, globals.h, track.c, draw.c, edit.c, canvas.c:
	We can now toggle an atom's visibility with the SHIFT-mouse1
	combination. To view _invisible_ atoms, we can now use SHIFT-mouse2.

	* canvas.c: *** empty log message ***

1998-07-27  Matt Hodges  <MPHodges@member.fsf.org>

	* translate.c, frames.c, rotate.c, edit.c, file.c:
	Added flag to update_bond_matrix parameters. This dictates whether an
	update _must_ occur. We force an update if a new file is loaded or if
	we are editing the positions and not _all_ of the atoms are being
	rotated or translated.

	This means we no longer have to keep the file_counter, though we keep
	track of bdfd_factor and hbdfd_factor from call to call of
	update_bond_matrix.

1998-07-25  Matt Hodges  <MPHodges@member.fsf.org>

	* menus.c, file.c:
	Changes made so that the current set of atoms (in the current
	orientation) can be merged with the atoms from a file on disk. This
	respects whether or not the atoms are visible, and if they are not,
	then they will disappear permanently from memory.

	This does not affect the state of the file from which the atoms were
	originally loaded.

1998-07-16  Matt Hodges  <MPHodges@member.fsf.org>

	* ToDo.txt: *** empty log message ***

	* README: Updated version.

	* Makefile.orig, Makefile:
	Alterered dependencies for files that need -D stuff.

	* rotate.c, view.c, globals.h, menus.c, frames.c, draw.c, file.c, canvas.c:
	Ripped out vectors code for the time being.

1998-07-14  Matt Hodges  <MPHodges@member.fsf.org>

	* Makefile.orig, Makefile:
	Changed name of saved tar file from XMakemol_[...] to XMakemol-[...].

	* Makefile.orig, Makefile:
	Moved some of the conditional compilation stuff which applys only to
	one or two files to the appropriate places.

	* canvas.c:
	xm_logo_read and xm_logo_pix should have been between an #ifdef XPM
	... #endif conditional.

	* file.c:
	When the bonds are assigned, it is irrelevant whether or not bond_flag
	is true or not. This conditional has been removed. It was a throwback
	to when the bond_matrix was reassigned when the bonds were turned on
	and off.

1998-07-13  Matt Hodges  <MPHodges@member.fsf.org>

	* edit.c, file.c:
	The bond factors/scales are now kept after canceling the edit dialogs.
	The values are reset when a new file is loaded.

1998-07-10  Matt Hodges  <MPHodges@member.fsf.org>

	* control.c, file.c:
	The depth and scale values are now kept after canceling the
	perspective dialog. The values are reset when a new file is loaded.

	* Makefile.orig, Makefile: Removed some of the files archived.

	* animate.c:
	When saving an XYZ animation, the screen is not affected in the
	interest of efficiency.

	* animate.c:
	The Animate dialog now has "Start", "Stop" and "Save" buttons similar
	to the Frames dialog so that an animation can be interrupted.

	* frames.c: Fixed typo.

	* animate.c:
	The status of the animation is now echoed to the message area as the
	animation proceeds.

	* ToDo.txt: New file.

1998-07-09  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c:
	Some changes associated with unneeded calls to update_bond_matrix and
	the allocation of colours.

	* edit.c: Cosmetic changes.

	* bbox.c, canvas.c: Don't bomb out if colour not allocated.

	* file.c: bond_tol was redundant. It has been removed.

	* file.c: global_vector taken into account when writing all frames.

	* animate.c:
	Changed the now-obselete writing of the number of frames in the first
	line of an animated XYZ file.

	* file.c:
	write_ascii_all now writes the coordinates as seen on the screen
	rather than as stored in frames.

	* file.c:
	write_ascii_frame now writes the coordinates as seen on the screen
	rather than as stored in frames.

	* elements: New file.

1998-07-08  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c:
	Removed unnecessary printing of the number of frames when writing an
	XYZ file.

	* README: New file.

	* INSTALL: Update usage of XM_ELEMENTS.

	* canvas.c:
	Only create the pixmap from the XPM data if there are 0 atoms when we
	start up.

	* frames.c:
	When popping up the frames dialog the title from the first frame was
	always used. This has been corrected.

	* file.c:
	Reinstated EPS code - now consistent (more or less) with code in
	canvas.c.

	* canvas.c:
	Write error about not being able to show the logo to the message area
	rather than stdout.

	* canvas.c:
	Check to see if we can show the XMakemol logo or not ie is it created
	correctly? If not, we don't try and show it as this would result in a
	BadDrawable error.

	* file.c, animate.c:
	Removed the now spurious ASCII references from file reading/writing.

	* Makefile.orig, Makefile:
	Default location for ELEMENTS reinstated. This can be overridden with
	the XM_ELEMENTS environment variable.

	* file.c:
	Made the use of XM_ELEMENTS optional; it can now override the default
	location as specified in ELEMENTS (see Makefile).

	* edit.c: Reversed calls of update_bbox and update_selected in
	count_visible_atoms as update_selected updates the display with the
	new set of visible atoms but with the old bounding box. This caused a
	bit of a judder.

1998-07-07  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c: Removed comment + tidied up.

	* edit.c: Print how many atoms are visible is the message area.

	* file.c:
	Bonds and H-bonds seem to be working. Still the PostScript output to
	update.

	* canvas.c: Drawing of H-bonds seems OK at present.

	* bonds.h: Introduced hbond_adjacency_list.

	* view.c: *** empty log message ***

	* view.c:
	No longer need call to update_bond_matrix when switching bonds on and
	off.

	* canvas.c: Drawing of H-bonds disabled at the moment.

	* file.c:
	Bond allocation and deallocation of memory seems OK. Next, the
	H-bonds.

1998-07-03  Matt Hodges  <MPHodges@member.fsf.org>

	* canvas.c: Still buggy.

	* bonds.h: bond_matrix has been removed.

	* file.c: write_eps is currently out of action.

	* canvas.c: Linked list sort of working. Must iron out bugs.

	* bonds.h: Moved bond_adjacency_list to this file.

	* file.c: Now generating linked lists for bonded atoms.

	* Makefile, Makefile.orig: Added bond.h dependencies.

	* globals.h: types_matrix moved from here to file.c.

	* file.c: types_matrix moved here from globals.h.

	* canvas.c: Included bonds.h.

	* file.c: Changed FILEC to FILE_C. Included bonds.h.

	* bonds.h: bond_matrix and hbond_matrix moved to here.

	lines above or below the atoms. Previously, this was achieved using a
	global variable.

	* view.c:
	Echo "Vectors are not available" when turning on/off the vectors
	switch if no vectors have been loaded.

	* INSTALL: New file.

	* Makefile:
	ELEM_FILE no longer set in Makefile - use XM_ELEMENTS environment
	variable instead.

	* Makefile: New file.

	* file.c:
	Now get the elements file from the environment variable XM_ELEMENTS.
	This allows element files on a per user basis, making personal
	customization possible.

1998-06-23  Matt Hodges  <MPHodges@member.fsf.org>

	* file.c:
	Now deallocating frames before they are allocated. This fixed a memory
	leak.

	* file.c: New file.

1998-04-03  Matt Hodges  <MPHodges@member.fsf.org>

	* animate.c: entered into RCS
