2010-06-08
	* added configurable key shortcuts for snap+direction player actions
	  (probably most useful for recording tool-assisted speedrun (TAS)
	  tapes using the single-step mode of the tape recorder)

2010-05-28
	* version number set to 3.3.0.1

2010-05-25
	* version 3.3.0.0 released

2010-05-22
	* fixed missing memory allocation in SP engine when saving engine data
	  for non-SP game engine snapshots (which also stores SP engine part)

2010-05-21
	* fixed problem with scrolling in native EM engine in multi-user mode
	  (this bug was just introduced with the experimental viewport stuff)
	* fixed animation of splashing acid in EM engine with classic artwork
	* fixed animation of cracking nut in EM engine with classic artwork
	* fixed (implemented) single step mode in native EM and SP engines
	* fixed "latest_engine" flag in classic levels (moved to single sets)
	* updated SDL library DLLs for Windows to the latest release versions
	  (this fixed some mysterious crashes of the game on Windows systems)
	* replaced EM and SP set in classic level set with native level files
	* finally added a newly written "CREDITS" file to the game package
	* removed sampled music loops from classic music set

2010-04-20
	* changed native Emerald Mine engine to support different viewport sizes

2010-04-19
	* changed native Supaplex engine to support different viewport sizes

2010-04-07
	* added initial, experimental support for different viewport properties
	  (with "viewports" being menu/playfield area and doors; currently the
	  size of the menu/playfield area and door positions can be redefined)

2010-04-02
	* added initial, experimental support for different window sizes

2010-03-27
	* added support for native Sokoban solution files in pure 'udlrUDLR'
	  format with extension ".sln" instead of ".tape" for solution tapes

2010-03-26
	* added image config suffix ".class" to be able to define classes of
	  crumbled elements which are then separated against each others when
	  drawing crumbled borders (class names can freely be defined)
	  (Example: "sand.CRUMBLED.class: sand" and "emc_grass.CRUMBLED.class:
	  emc_grass" results in sand and emc_grass being crumbled separately,
	  even if directly adjacent on the playfield.)
	* added image config suffix ".style" to use two new features for
	  crumbled graphics:
	  - "accurate_borders": try to draw correctly crumbled corners (which
	    means that a row of crumbled elements does not have two crumbled
	    corners for each element in the row, but only at the "real" corners
	    at the start and the end of the row of elements)
	  - "inner_corners": also draw inner corners in concave constructions
	    of several crumbled elements -- this is currently a big kludge: the
	    number of frames for crumbled graphic must be "2", with the first
	    frame as usual (crumbled graphic), while the second frame contains
	    the graphic with inner (crumbled) corners for the crumbled graphic
	  (These two features are mainly intended for bevelled walls, not for
	  diggable elements like sand; "inner_corners" only works reliably for
	  static walls, not for in-game dynamically changing walls using CEs.)

2010-03-16
	* finished code cleanup of native Supaplex game engine

2010-03-14
	* started code cleanup of native Supaplex game engine

2010-03-13
	* integrated playing sound effects into native Supaplex game engine

2010-03-10
	* added configurable key shortcuts for the tape recorder buttons

2010-03-09
	* added (hidden) function to save native Supaplex levels with tape as
	  native *.sp file containing level with demo (saved with a file name
	  similar to native R'n'D levels, but with ".sp" extension instead of
	  ".level"); to use this functionality, enter ":save-native-level" or
	  ":snl" from the main menu with the native Supaplex level loaded and
	  the appropriate tape loaded to the tape recorder
	* fixed potential crash bug caused by illegal array access in engine
	  snapshot loading and saving code
	* changed setting permissions of score files to be world-writable if
	  the program is not installed and running setgid to allow the program
	  to modify existing score files when run as a different user (which
	  allows cheating, of course, as the score files are not protected
	  against modification in this case)
	* added (commented out) suggestions for RO_GAME_DIR and RW_GAME_DIR to
	  the top level Makefile for Debian / Ubuntu installations
	* added saving read-only levels from editor into personal level set
	  (thanks to Bela Lubkin for the above four patches)

2010-03-03
	* added updating of game values on the panel to Supaplex game engine

2010-02-23
	* finished integrating R'n'D graphics engine into Supaplex game engine
	  (although some animations do not support full customizability yet)

2010-02-22
	* done integrating R'n'D graphics engine into file "Infotron.c"
	* done integrating R'n'D graphics engine into file "OrangeDisk.c"

2010-02-19
	* integrated engine snapshot functionality into Supaplex game engine

2010-02-16
	* fixed bug in native Supaplex engine that broke several demo solutions
	* fixed bug with re-initializing already existing elements in function
	  RelocatePlayer() in src/game.c (causing problems with Sokoban fields
	  counted a second time, making the currently playing level unsolvable)
	* done integrating R'n'D graphics engine into file "SnikSnaks.c"
	* done integrating R'n'D graphics engine into file "Electrons.c"
	* done integrating R'n'D graphics engine into file "Zonk.c"

2010-02-14
	* done integrating R'n'D graphics engine into file "Murphy.c"
	* done integrating R'n'D graphics engine into file "BugsTerminals.c"

2010-02-07
	* started integrating R'n'D graphics engine into Supaplex game engine

2010-02-02
	* added small kludge that allows transparent pushing animation over
	  non-black background (by using "game.use_masked_pushing: true")
	* added editor flag to Sokoban field/object elements to automatically
	  finish solved Sokoban style levels (even if they contain non-Sokoban
	  elements, which prevents auto-enabling this feature for such levels)

2010-01-10
	* added new element "from_level_template" which is replaced by element
	  from level template at same playfield position when loaded (currently
	  not accessible from level editor, but only used for special Sokoban
	  level conversion when using "special_flags: load_xsb_to_ces")
	* added special behaviour for "special_flags: load_xsb_to_ces": global
	  settings of individual level files are overwritten by template level
	  (except playfield size, level name, level author and template flag)

2010-01-07
	* added handling of gravity ports when converting Supaplex style R'n'D
	  levels to native Supaplex levels for playing with Supaplex engine

2010-01-06
	* fixed bug in Supaplex engine regarding initial screen scroll position

2009-12-17
	* fixed EMC style pushing animations in the R'n'D graphics engine (when
	  using ".2nd_movement_tile" for animations having start and end tile)
	* for this to work (look) properly for two-tile pushing animations with
	  non-black (i.e. opaque) background, the pushing graphics drawing order
	  was changed to first draw the pushed element, then the player (maybe
	  this should be controlled by an ".anim_mode" flag yet to be added)
	* two-tile animations for moving or pushing should have 7 frames for
	  normal speed, 15 frames for half speed etc. to display correct frames
	* two-tile animations are also displayed correctly with different speed
	  settings for the player (for pushing animations) or moving elements

2009-12-16
	* added searching for template level (file "template.level") not only
	  inside the level set directory, but also in above level directories;
	  this makes is possible to use the same single template level file
	  (placed in a level group directory) for many level sub-directories

2009-12-10
	* fixed bug with steel exit being destructible during opening phase
	* added token "special_flags" to "levelinfo.conf" (currently with the
	  only recognized value "load_xsb_to_ces", doing the same as the flag
	  "-Dload_xsb_to_ces" on the command line, but as a permanent flag for
	  converting all elements in native (XSB) Sokoban level files to CEs)

2009-12-08
	* fixed some problems with Supaplex engine when compiling for Windows

2009-12-05
	* added special mode to convert elements of Sokoban XSB levels to CEs
	  by adding "-Dload_xsb_to_ces" to the command line starting the game
	  (also adding a dependency to a template level file "template.level")

2009-12-01
	* added reading native Sokoban levels and level packages (XSB files)

2009-11-25
	* fixed bugs in (auto)scrolling behaviour when passing ports or when
	  wrapping around the playfield through "holes" in the playfield border

2009-11-24
	* changed internal playfield bitmap handling from playfield sized bitmap
	  to screen sized bitmap (visible scrolling area), therefore speeding up
	  graphics operations (by eliminating bitmap updates in invisible areas)
	  and removing playfield size limitations due to increasing bitmap size
	  for larger playfield sizes (while the new implementation always uses
	  a fixed playfield bitmap size for arbitrary internal playfield sizes)

2009-11-12
	* fixed bug with single step mode (there were some cases where the game
	  did not automatically return to pause mode, e.g. when trying to push
	  things that cannot be pushed or when trying to run against a wall)

2009-11-01
	* added support for loading Supaplex levels in MPX level file format

2009-10-31
	* fixed SP engine to set "game over" not before lead out counter done

2009-10-30
	* fixed (potential) compile error when using GCC option "-std=gnu99"
	  (thanks to Tom "spot" Callaway)

2009-10-28
	* fixed array allocation in native Supaplex engine to correctly handle
	  preceding scratch buffers (needed because of missing border checking)
	* fixed playfield initialization to correctly add raw header bytes as
	  subsequent scratch buffer (needed because of missing border checking)

2009-10-24
	* most important parts of native Supaplex engine integration working:
	  - native Supaplex levels can be played in native Supaplex engine
	  - native Supaplex level/demo files ("*.sp" files) can be re-played
	  - all 111 classic original Supaplex levels automatically solvable
	  - native Supaplex engine can be selected and used from level editor
	  - logic of re-playing Supaplex demos migrated to R'n'D tape logic

2009-09-25
	* fixed another translation problem from VisualBasic to C (where "int"
	  should be "short") causing unsolvable demos with bugs and terminals
	  ("bugs" being related to the Supaplex "buggy base" element here ;-) )

2009-09-23
	* fixed bug when reading Supaplex single level files (preventing loader
	  from seeking to level position like in Supaplex level package files)

2009-08-01
	* first classic Supaplex level running and solved by solution/demo tape

2009-06-20
	* started with integration of native Supaplex engine, using source code
	  of Megaplex from Frank Schindler, based on original Supaplex engine

2009-06-16
	* version number set to 3.2.6.2

2009-06-15
	* version 3.2.6.1 released

2009-05-31
	* fixed bug with element_info[e].gfx_element not being initialized in
	  early game stage, causing native graphics in EMC level sets to be
	  mapped completely to EL_EMPTY (causing a blank screen when playing)
	  (this only happened when starting the program with an EMC set with
	  native graphics, but not when switching to such a set at runtime)

2009-03-30
	* deactivated blit-to-same-surface workaround again (see 2009-03-24)
	  and using self-compiled, patched SDL.dll that solves this problem
	  (interim solution until release of SDL 1.2.14 that should fix this)

2009-03-26
	* extended backwards compatibility mode to allow already fixed bug with
	  change actions (see "2008-02-05") for existing levels (especially the
	  Zelda and Zelda II levels and other cool stuff by Alan Bond like FMV)

2009-03-24
	* reactivated workaround to prevent program crashes due to blitting to
	  the same SDL surface that apparently only occurs on Windows systems
	  (this is no final solution; this problem needs further investigation)

2008-11-05
	* version number set to 3.2.6.1

2008-11-04
	* version 3.2.6.0 released

2008-10-11
	* fixed behaviour of player option "no centering when relocating" which
	  was incorrect when disabled and relocation target inside visible area
	  and "no scrolling when relocating" enabled at the same time

2008-10-06
	* fixed problems with re-mapping players on playfield to input devices:
	  previously, players found on the level playfield were changed to the
	  players connected to input devices (for example, player 3 in the level
	  was changed to player 1 (using artwork of player 3, to be able to use
	  a player with a different color)); this had the disadvantage that CE
	  conditions using player elements did not work (because the players in
	  the level definition are different to those effectively used in-game);
	  the new system uses the same player elements as defined in the level
	  playfield and re-maps the input devices of connected players to the
	  corresponding player elements when playing the level (in the above
	  example, player 3 now really exists in the game and is moved using the
	  events from input device 1); level tapes still store the events from
	  input devices 1 to 4, which are then re-mapped to players accordingly
	  when re-playing the tape (just as it is done when playing the level)

2008-09-29
	* fixed bug with player relocation while the player switches an element

2008-09-24
	* fixed bug with EM/DC style exit and EM/DC style steel exit which was
	  not walkable (and did not let the player enter) when in process of
	  opening, but not fully open yet (which can cause the player not being
	  able to enter the exit in EM/DC style levels in time)

2008-08-02
	* fixed some bugs regarding the new level/CE random seed reset options

2008-07-14
	* moved "level settings" and "editor settings" to two tabbed screens in
	  level editor to gain space for additional level property settings
	* added level setting to start a level with always the same random seed
	* added CE action "set random seed" to re-initialize random seed in game
	  (this is the only CE action that gets executed before the CE changes,
	  which is needed to use the newly set random seed during the CE change)

2008-06-16
	* fixed redraw problem of special editor door when playing from editor

2008-06-16
	* fixed initialization of gfx_element for level sketch image creation

2008-06-15
	* added switch for EM style dynamite "[ ] explodes with chain reaction"
	  (with default set to "on" for existing levels, but "off" for all new
	  levels), as EM style dynamite does not chain-explode in original EM

2008-02-05
	* added optional initial inventory for players (pre-collected elements)
	* added change page actions "set player inventory" and "set CE artwork"
	* added recognition of "player" parameter on change pages when player
	  actions are defined, but no trigger player in corresponding condition
	  (this resulted in actions that only affected the first player before)
	* fixed bug with change actions being executed for newly created custom
	  elements resulting from custom element changes, when the intention was
	  only to check for change actions for the previous custom element

2008-02-03
	* changed design and size of element drawing area in level editor
	* added "element used as action parameter" to element change actions

2008-01-27
	* added possibility to reanimate player immediately after his death
	  (for example, by "change to <player> when explosion of <player>")

2008-01-25
	* fixed bug with "gray" white door not being uncovered by magnifier
	* added score for collecting (any) key to the white key config page

2008-01-22
	* added condition "deadly when <getting hit by>" for custom elements
	  that behaves a bit like the existing "deadly when <colliding with>",
	  but with the following differences:
	  - it only kills players or friends when it was moving before it hits
	  - it does not kill players or friends that try to run into it

2008-01-21
	* fixed the following change conditions where a player element is used
	  as the "element that is triggering the custom element change":
	  - touching <element>
	  - hitting <element>
	  - explosion of <element>
	  - move of <element>
	  (the last two conditions already worked partially, but only for the
	  first player, and not for the "Murphy" player when using "move of")

2008-01-20
	* fixed crash bug caused by accessing invalid element (with value -1)
	  in UpdateGameControlValues()
	* fixed graphical bug when using two-tile movement animations with EMC
	  game engine without explicitly using native EMC graphics engine

2007-10-31
	* fixed bug in new "can dig" feature (see below) so that an unsuccessful
	  try to push something (due to push delay) does not cause a dig action

2007-10-29
	* fixed bug with reference elements used as trigger elements on custom
	  element change pages not being recognized
	* fixed bug with reference elements not being removed from the playfield
	* added engine functionality that allows custom elements that "can dig"
	  other elements not only to do so when moving by themselves, but also
	  when being pushed by the player (therefore adding the functionality to
	  push one element over another element, replacing it with the new one)

2007-10-23
	* added command line function to write level sketch images to directory

2007-10-20
	* merged override and auto-override options into new override options
	  with a new data type than can take the values "no", "yes" and "auto"

2007-10-18
	* fixed growing steel wall to also leave behind steel wall instead of
	  normal, destructible wall
	* fixed handling of rocks falling through stacks of quicksand with
	  different speed (before, the rocks just got stuck in the quicksand)

2007-10-09
	* fixed nasty bug with auto-override and normal override not working on
	  program startup (especially when current level set has custom artwork)

2007-10-05
	* version 3.2.5 released as special edition "R'n'D jue"

2007-10-05
	* fixed X11 crash bug when blitting masked title screens over background

2007-10-04
	* changed build system to support special editions (like "R'n'D jue")
	* added (hardcoded) loading graphics for "R'n'D jue" special edition
	* fixed X11 crash bug when scaling images with width/height less than 32

2007-09-27
	* added "background.PLAYING" (only visible as two-pixel border in game)
	* added default level set for first start of special R'n'D version
	* changed door animations for editor always behaving like "quick doors"

2007-09-26
	* added new custom artwork setup option "auto-override non-CE sets" for
	  automatic artwork override that is only used for level sets without
	  custom element artwork (as it does not make much sense to override
	  any artwork that redefines custom element artwork for sets using CEs)
	* fixed default artwork for "special" R'n'D versions always using the
	  "classic" artwork as the base if base artwork is not explicitly
	  defined in "levelinfo.conf", regardless of different default artwork
	  used by the special R'n'D version -- this is needed because any such
	  custom artwork is designed using the "classic" artwork definitions as
	  the base (including menu definitions and screen positions etc., which
	  would otherwise be taken from the different special default artwork)

2007-09-17
	* fixed drawing of animated "quicksand.filling" and "quicksand.emptying"
	  for both EMC and R'n'D graphics engine (heavy workarounds needed due
	  to massively broken handling of quicksand in R'n'D game engine)
	* fixed off-limits access to array in DrawLevelFieldCrumbledSandExt()
	* fixed crash bug (hopefully) when scrolling with cursor keys in editor

2007-09-16
	* fixed small bug in toon drawing (introduced when fixing the crash bug)

2007-09-15
	* added graphics definition "game.panel.highscore" to display the
	  current levels current high score in the game panel

2007-09-13
	* version number set to 3.2.5

2007-09-13
	* version 3.2.4 released

2007-09-13
	* fixed crash bug in toon drawing functions for large step offset values

2007-09-12
	* fixed some problems with displaying game panel when quick-loading tape

2007-09-07
	* fixed (experimental only) redrawing of every tile per frame (even if
	  unneeded) for the extended (R'n'D based) EMC graphics engine
	* added optimization to only calculate element count for panel display
	  if really needed (that is, if element count values defined on panel)
	* fixed problem with special editor door redraw when entering main menu

2007-09-03
	* fixed bug with displaying background for title messages on info screen
	* some code cleanup for the extended (R'n'D based) EMC graphics engine

2007-09-01
	* fixed bug with CE action "move player" always resulting in player 4
	  if there was a CE action with no trigger player (because the player
	  element was calculated by using log_2() from trigger player bits with
	  the value PLAYER_BITS_ANY) -- this is now fixed by also storing the
	  triggering player bit mask and handling all players in "move player"
	* fixed bug when defined artwork cannot be found for artwork that has
	  default artwork cloned from other artwork (without default filename)
	* added several fixes to the extended (R'n'D based) EMC graphics engine

2007-08-26
	* fixed broken editor copy and paste for custom elements between levels

2007-08-25
	* title messages are now also searched in graphics artwork directory;
	  those found in graphics directory have precendence over those found
	  in level directory -- this handles title messages stored in graphics
	  directories as part of the artwork set, just like title images; this
	  makes sense, as corresponding special font definitions for messages
	  are usually defined in the same graphics artwork directory, and also
	  because title images and title messages that are combined in a level
	  set introduction should usually not be separated when the level set
	  is used with a different artwork set (e.g. using "override graphics")
	* fixed problem with door borders on main screen by first drawing doors
	  and then the corresponding border masks, but not vice versa
	* fixed problem with artwork config entries using the value "[DEFAULT]";
	  this does not what one might expect, but sets the value to an invalid
	  value -- solution: simply ignore such entries, which results in this
	  value keeping its previous (real) default value (in general, entries
	  that should use their default value should just not be defined here)
	* fixed problem with wrong fading area size from main menu to setup menu

2007-08-22
	* fixed problem with broken crumbled graphics after level set changes
	  when using R'n'D custom artwork with level sets using the EMC engine

2007-05-07
	* fixed invisible "joysticks deactivated ..." text on setup input screen

2007-04-27
	* added use of hashes created from static lists (element tokens, image
	  config, font tokens) to speed up lookup of configuration parameters
	* fixed bug where element and graphic config token lookup was mixed up

2007-04-26
	* added "busy" animation when initializing program and loading artwork
	* added initialization profiling for program startup (debugging only)

2007-04-25
	* fixed(?) very strange bug apparently triggered by memset() when code
	  was cross-compiled with MinGW cross-compiler for Windows XP platform
	  (this only happened when using SDL.dll also self-compiled with MinGW)

2007-04-19
	* added graphics engine directive "border.draw_masked_when_fading" that
	  enables/disables drawing of border mask over screen that is just faded

2007-04-18
	* fixed small problem with separate fading definition for game screen

2007-04-14
	* added additional configuration directives for setup screen draw offset
	  menu.draw_xoffset.SETUP[XXX] and menu.draw_yoffset.SETUP[XXX] with XXX
	  in GAME, EDITOR, GRAPHICS, SOUND, ARTWORK, INPUT, SHORTCUTS_1,
	  SHORTCUTS_2, CHOOSE_ARTWORK, CHOOSE_OTHER (where "CHOOSE_ARTWORK" is
	  used to define draw offset on custom artwork selection screens and
	  "CHOOSE_OTHER" is used on all other list style selection screens, like
	  choosing game speed or screen mode for fullscreen mode)
	* added additional configuration directives to define main menu buttons:
	  - menu.button_name	and menu.button_name.active
	  - menu.button_levels	and menu.button_levels.active
	  - menu.button_scores	and menu.button_scores.active
	  - menu.button_editor	and menu.button_editor.active
	  - menu.button_info	and menu.button_info.active
	  - menu.button_game	and menu.button_game.active
	  - menu.button_setup	and menu.button_setup.active
	  - menu.button_quit	and menu.button_quit.active
	* added eight pure decoration graphic definitions for the game panel

2007-04-08
	* added support for accessing native Diamond Caves II level packages
	* fixed displaying of game panel values for Emerald Mine game engine
	* fixed displaying end-of-level time and score values on new game panel

2007-04-07
	* added game panel control to display arbitrary elements on game panel
	* added game panel control to display custom element score (globally
	  unique for identical custom elements) either as value or as element
	* added ".draw_masked" and ".draw_order" to game panel control drawing

2007-04-05
	* fixed some general bugs with handling of ".active" elements and fonts

2007-04-04
	* cleanup of game panel elements (some elements were not really needed)
	* added displaying of gravity state (on/off) as new game panel control
	* added animation for game panel elements (similar to game elements)

2007-04-03
	* added new pseudo game mode "PANEL" to define panel fonts and graphics
	  - panel fonts now use ".PANEL" suffix instead of ".PLAYING" suffix
	  - panel graphics now use ".PANEL" suffix instead of ".DOOR" suffix
	  (else graphics would have to use ".PLAYING", which would be confusing)
	* fixed bug when fading out to game screen with border mask defined

2007-04-02
	* added attribute ".tile_size" for element style game panel controls

2007-04-01
	* added <space> key as additional valid key to use for confirm requester

2007-03-31
	* improved menu fading, adding separate fading definitions for entering
	  and leaving a "content" screen (in general), and optional definitions
	  for the special "content" screens SCORES, EDITOR, INFO and PLAYING

2007-03-30
	* added (currently invisible) setup option to define scroll delay value
	* fixed small bug in priority handling when auto-detecting level start
	  position in levels without player element (but player from CE etc.)
	* added option "game.forced_scroll_delay_value" to override user choice
	  of scroll delay value for certain level sets with "graphicsinfo.conf"
	* replaced setup option "scroll delay: on/off" by new setup option that
	  directly allows selecting the desired scroll delay value from 0 to 8

2007-03-28
	* added displaying of most game panel control elements (not animated)

2007-03-26
	* added new configuration directives to display additional game engine
	  values on the game control panel, like the following examples:
	  - game.panel.time_hh/time_mm/time_ss	- level time in HH/MM/SS format
	  - game.panel.penguins			- number of penguins to rescue
	  - game.panel.level_name		- level name of current level

2007-03-24
	* added support for preview tile sizes "1" and "2" (1x1 and 2x2 pixels)

2007-03-23
	* added new player option "no centering when relocating" for "invisible"
	  teleportations to level areas that look exactly the same, giving the
	  illusion that the player did not relocate at all (this was the default
	  since 3.2.3, but caused visual problems with room creation in "Zelda")
	* added new menu fading effect "melt", shamelessly stolen from "DOOM"

2007-03-21
	* improved menu fading, adding separate fading definitions for entering
	  and leaving a menu and for fading between menu and "content" screens
	* fixed small bug with recognizing also ".font_xyz" style definitions

2007-03-20
	* improved menu fading, adding separate fading definitions for fading
	  between menu screens and fading between menu and "destination" screens

2007-03-19
	* titlemessage_initial_x and titlemessage_x set to "[DEFAULT]" in static
	  configuration (set from "[titlemessage_initial]" and "[titlemessage]")
	* fading settings of "[titlemessage_initial]" and "[titlemessage]" set
	  to "[DEFAULT]" in static configuration (set from "[title_initial]" and
	  "[title]")
	* improved title fading, allowing fading animation types "none", "fade"
	  and "crossfade" (including cross-fading of last title to main menu)

2007-03-18
	* added configurability of graphics, sounds and music for title screens,
	  which are separated into initial title screens (only shown once at
	  program startup) and title screens shown for a given level set; these
	  title screens can be composed of up to five title images and up to
	  five title text messages (each drawn using an optional background
	  image), also using background music and/or sounds; aspects like
	  background images, sounds and music of title screens can either be
	  defined generally (valid for all title screens) or specifically (and
	  therefore differently for each title screen) using these directives:

	  to define a background image, sound or music file for all screens:
	  - background.TITLE_INITIAL (for all title screens for game startup)
	  - background.TITLE         (for all title screens for level sets)

	  to define a background image, sound or music file for a single screen:
	  - background.titlescreen_initial_x  (with x in 1,2,3,4,5)
	  - background.titlescreen_x          (with x in 1,2,3,4,5)
	  - background.titlemessage_initial_x (with x in 1,2,3,4,5)
	  - background.titlemessage_x         (with x in 1,2,3,4,5)

	  to define the title screen images:
	  - titlescreen_initial_x             (with x in 1,2,3,4,5)
	  - titlescreen_x                     (with x in 1,2,3,4,5)

	  to define the title text messages, place text files into the level set
	  directory that have the following file names:
	  - titlemessage_initial_x.txt        (with x in 1,2,3,4,5)
	  - titlemessage_x.txt                (with x in 1,2,3,4,5)

	  to define the properties of the text messages, either use directives
	  that affect all text messages:
	  - [titlemessage_initial].<suffix>
	  - [titlemessage].<suffix>
	  or use directives that affect single text messages:
	  - titlemessage_initial_x.<suffix>   (with x in 1,2,3,4,5)
	  - titlemessage_x.<suffix>           (with x in 1,2,3,4,5)

	  valid values for <suffix> are the same as for readme.<suffix> below;
	  use ".sort_priority" (default: 0) to define an arbitrary order for
	  title images and title messages (which can therefore be mixed)

2007-03-14
	* added full configurability of "readme.txt" screen appearance:
	  - readme.x:              <left position used with alignment>
	  - readme.y:              <top position>
	  - readme.width:          <maximim text width in pixels>
	  - readme.height:         <maximum text height in pixels>
	  - readme.chars:          <maximum number of chars per line>
	  - readme.lines:          <maximum number of lines displayed>
	  - readme.align:          left,center,right (default: center)
	  - readme.top:            top,middle,bottom (default: top)
	  - readme.font:           font name
	  - readme.autowrap:       true,false (default: true)
	  - readme.centered:       true,false (default: false)
	  - readme.parse_comments: true,false (default: true)
	  - readme.sort_priority:  (not used here, but only for title screens)
	  when "readme.chars" and/or "readme.lines" is set to "-1" (this is the
	  default), they are automatically determined from "readme.width" and
	  "readme.height" accordingly; when they are not "-1", they have
	  precedence over "readme.width" and "readme.height"
	* added internal ad-hoc config settings for displaying text files like
	  title messages or "readme.txt" style level set info files:
	  - .font:           font name  (default: readme.font)
	  - .autowrap:       true,false (default: readme.autowrap)
	  - .centered:       true,false (default: readme.centered)
	  - .parse_comments: true,false (default: readme.parse_comments)
	  (the leading '.' and the separating ':' are mandatory here); to use
	  these ad-hoc settings, they have to be written inside a comment, like
	  "# .autowrap: false" or "# .centered: true"; these settings then
	  override the above global settings (they can even be used more than
	  once, like "# .centered: true", then some text that should be drawn
	  centered, then "# .centered: false" to go back to non-centered text;
	  important note: after using "# .parse_comments: false", or when using
	  "readme.parse_comments: false", detecting and parsing comments inside
	  the file is disabled and comments are just printed like normal text;
	  also be aware that all automatic text size calculations are done with
	  the font defined in "readme.font", while using different fonts using
	  "# .font: <font>" inside the text file may cause unexpected results

2007-03-08
	* changed some numerical limits in the level editor from 255 to 999

2007-03-07

2007-03-01
	* added new (special) "include: <filename>" directive that works in all
	  configuration files (like "graphicsinfo.conf") and that has the same
	  effect as if that directive would be replaced with the content of the
	  specified file (this can be useful to split large configuration files
	  into several smaller ones and include them from one main file, or to
	  store configuration settings that always stay the same into a separate
	  file, while including it and only add those parts that really change)

2007-02-24
	* fixed minor bug (screen redraw of player tiles) in EMC graphics engine

2007-02-23
	* fixed bug in "InitMovingField()" where treating an integer array as
	  boolean caused wrong resetting of animations while elements are moving

2007-02-08
	* added sort priority for order of title screens and title messages

	* re-enabled quitting of lost game by pressing space or return again
	* added blanking of mouse pointer when displaying title screens
	* added remaining menu draw offset definitions for info sub-screens

	* improved handling of title text messages (initial and for level set)

2007-02-03
	* added new options "auto-wrap" and "centered" for DC2 style envelopes

2007-01-31
	* fixed displaying and typing of player name when it is centered
	* added special characters to be allowed for player name (not only A-Z)

2007-01-25

2007-01-21
	* fixed small cosmetical bug with underlining property tabs in editor

	  - white key and gate (one white key needed for each white gate)
	  - fake gate (there is no key to open/pass this kind of gate!)
	  - extended magic wall which also handles pearls and crystals
	  - fast quicksand

2007-01-14
	* changed maximum value for endless loop detection to a higher value
	  (some levels really used very deep recursion without being endless)

2007-01-13
	* added new elements for newly supported Diamond Caves II levels:
	  - growing steel walls

2007-01-04
	* fixed malloc/free bug when updating EMC artwork entries in level list
	* added workaround (warning and request to quit the current game) when
	  changing elements cause endless recursion loop (which would otherwise
	  freeze the game, causing a crash-like program exit on some systems)

2006-12-16
	* fixed nasty string overflow bug when entering too long envelope text

2006-12-05
	* added feedback sounds for menu navigation "menu.item.activating" and
	  "menu.item.selecting" (for highlighting and executing menu entries)

2006-12-03
	* improved "no scrolling when relocating" to also consider scroll delay
	  (meaning that the player is not automatically centered in this case;
	  this makes it possible to "invisibly" relocate the player to a region
	  of the level playfield which looks the same as the old level region)
	* fixed bug with not recognizing "main.input.name.align" when active

2006-12-02

	  screen than usual (with "menu.list_size.LEVELS" directive)
	* fixed crash bug (Windows/SDL only) caused by BlitBitmap blitting from
	  the backbuffer to the backbuffer by error (with identical rectangle)

2006-10-28
	* fixed bug when displaying titlescreen with size less than element tile
	* fixed bug that caused elements with "change when digging <e>" event
	  to change for _every_ digged element, not only those specified in <e>
	* fixed bug that caused impact style collision when dropping element one
	  tile over the player that can both fall down and smash players
	* fixed bug that caused impact style collision when element changed to
	  falling/smashing element over the player immediately after movement

2006-10-24
	* fixed bug that allowed making engine snapshots from the level editor

2006-10-22
	* fixed bugs with player name and current level positions on main screen

2006-10-20
	* added configuration directives for control of title screens:
	  - "title.fade_delay" for fading time
	  - "title.post_delay" for pause between screens (when not crossfading)
	  - "title.auto_delay" to automatically continue after some time
	  these settings can each be overridden by specifying them with titles:
	  - "titlescreen_initial_{1-5}.{fade_delay,post_delay,auto_delay}"
	  - "titlescreen_{1-5}.{fade_delay,post_delay,auto_delay}"
	  fading mode can also be specified:
	  - "titlescreen_initial_{1-5}.anim_mode: {fade,crossfade}
	  - "titlescreen_{1-5}.anim_mode: {fade,crossfade}
	  default is using normal fading for menues and initial title screens,
	  while using cross-fading for level set title screens
	* fixed bug with background not drawn in Hall of Fame after game was won

2006-10-18
	* added configuration directives for the remaining main menu items

2006-10-17
	* added additional configuration directives for info screen draw offset:
	  menu.draw_{x,y}offset.INFO[{ELEMENTS,MUSIC,CREDITS,PROGRAM,LEVELSET}]
	* added additional configuration directives for preview info text
	* limited mouse wheel sensitive screen area to scrollable screen area

2006-10-16

	* version number set to 3.2.3

2006-08-29
	* version 3.2.2 released

2006-08-29
	* fixed bug with redrawing screen in fullscreen mode after quick tape
	  reloading when using the EMC game engine
	* changed token names from "last_ce_[1-8]" to "prev_ce_[1-8]"

2006-08-28
	* fixed bug in GameWon() when level contains no exit (like in Sokoban)

2006-08-23
	* added engine snapshot functionality for instant tape reloading (this
	  only works for the last tape saved using "quick save", and does not
	  work across program restarts, because it completely works in memory)

2006-08-21
	* version number set to 3.2.2

2006-08-20
	* version 3.2.1 released

2006-08-20

2006-08-04
	* fixed bug with scrollbars inside editor when using the Windows mouse
	  enhancement tool "True X-Mouse" (which injects key events to the event
	  queue to insert selected stuff into the Windows clipboard, which gets
	  confused with the "Insert" key for jumping to the last editor cascade
	  block in the element list)
	* added Rocks'n'Diamonds icon for use as window icon to SDL version
	* added key shortcut "Alt + Enter" to toggle fullscreen mode at any time

2006-08-01

	  created in the R'n'D sub-directory of the personal documents directory
	* added Windows message box to direct to "stderr.txt" after error aborts

	* improved general scrollbar handling (when jump-scrolling scrollbars)

2006-07-23
	* changed scrollbars to always show last line as first after scrolling

	* fixed level time for EMC levels for V2 engine (V2 and V5 levels)
	* fixed special handling of vertically stacked acid becoming fake acid

2006-07-16
	* fixed bug (very special case) with CE_SCORE_GETS_ZERO, which can
	  affect multiple instances of the same CE, although this kind of
	  change condition usually only affects one single custom element

2006-07-16
	* version number set to 3.2.1

2006-07-16
	* version 3.2.0 released

	  (some compatibility settings being set not only after level loading)
	* fixed crash bug when number of custom graphic frames was set to zero
	* fixed bug with teleporting player on walkable tile not working anymore
	* added partial compatibility support for pre-release-only "CONF" chunk
	  (to make Alan Bond's "color cycle" demo work again :-) )

2006-05-30
	* fixed some bugs when displaying title screens from info screen menu
	* fixed bug which caused EMC doors #5 to #8 to be passable without keys

2006-05-20
	* changed file major version to 3 to reflect level file format changes
	* uploaded pre-release (test) version 3.2.0-8 binary and source code

2006-05-19
	* added new chunk "NAME" to level file format for level name settings
	* added new chunk "NOTE" to level file format for envelope settings
	* changed name of chunk "CONF" to "ELEM" (for normal element settings)
	* updated magic(5) file to recognize changed and new level file chunks
	* removed change events "change when CE value/score changes" as unneeded

2006-05-17

	* added new chunk "INFO" to level file format for global level settings
	* added all element settings from "HEAD" chunk to "CONF" chunk
	* added all global level settings from "HEAD" chunk to "INFO" chunk

2006-05-09
	* changed level file format by adding two new chunks "CUSX" (for custom
	  elements, replacing the previous "CUS4" chunk) and "GRPX" (for group
	  elements, replacing the previous "GRP1" chunk); these new IFF style
	  chunks use the new and flexible "micro chunks inside chunks" technique
	  already used with the new "CONF" chunk (for normal element properties)
	  which makes it possible to easily extend the existing level format
	  (instead of using fixed-length chunks like before, which are either
	  too big due to reserved bytes for future use, or too small when those
	  reserved bytes have all been used and even more data should be stored,
	  requiring the replacement by new and larger chunks just like it went
	  with "CUS1" to "CUS4"); this whole problem now does not exist anymore

2006-05-06
	* added credits pages to the "credits" section that were really missing
	* added some missing element descriptions to the level editor
	* added down position of switchgate switch to the level editor

	* fixed small bug that caused door sounds playing when music is enabled

2006-04-29
	* added the possibility to define up to five title screens for each
	  level set that are displayed after loading using (cross)fading in/out
	  (this was added to display the various start images of the EMC sets)

2006-04-28
	* added "CE score gets zero [of]" to custom element trigger conditions
	* added setup option to display element token name in level editor

2006-04-19

	* fixed bug when creating GE with walkable element under the player

2006-04-01
	* added use of "Insert" and "Delete" keys to navigate element list in
	  level editor to start of custom elements or start of group elements

2003-08-16	src/init.c
	* fixed bug which (for example) crashed the level editor when defining

	* fixed graphical bug of player digging/collecting/snapping element

	  "game.current_gravity" to prevent level setting from being changed
	  by playing the level (keeping the runtime value after playing)

	* fixed graphics bug when digging element that has 'crumbled' graphic
	  definition, but not 'diggable' graphic definition

2003-08-06

2002-08-25
	* version number set to 2.1.2

2002-08-13

2002-08-10
	* version number set to 2.1.1

2002-08-05
	* version 2.1.0 released
	
2002-05-19
	* version number set to 2.1.0

2002-04-03 to 2002-05-19	(various source files)
	* graphics, sounds and music now fully configurable
	* bug fixed that prevented walking through tubes when gravity on

2002-04-02	src/events.c, src/editor.c
	* Make Escape key less aggressive when playing or when editing level.
	  This can be configured as an option in the setup menu. (Default is
	  "less aggressive" which means "ask user if something can be lost"
	  when pressing the Escape key.)

2002-04-02	src/screen.c
	* Added "graphics setup" screen.

2002-04-01	src/screen.c
	* Changed "choose level" setup screen stuff to be more generic (to
	  make it easier to add more "choose from generic tree" setup screens).

2002-04-01	src/config.c, src/timestamp.h
	* Added source files "src/config.[ch]" and "src/timestamp.h" (which
	  automatically gets created by "src/Makefile" and contains an actual
	  compile-time timestamp to identify development versions of the game).

2002-03-31	src/tape.c, src/events.c
	* Added quick game/tape save/load functions to tape stuff which can be
	  invoked by a keyboard shortcut. Default: "F1" saves game/tape, "F2"
	  loads previously recorded tape and directly goes into recording mode
	  from the end of the tape (therefore appending to the tape).

2002-03-31	src/tape.c
	* Added "index mark" function to tape recorder. When playing or
	  recording, "eject" button changes to "index" button. Setting index
	  mark is not yet implemented, but pressing index button when playing
	  allows very quick advancing to end of tape (when normal playing),
	  very fast forward mode (when playing with normal fast forward) or
	  very fast reaching of "pause before end of tape" (when playing with
	  "pause before end" playing mode).

2002-03-30	src/cartoons.c
	* Moved some stuff from cartoons.c to the new "src/libgame/toons.c".

2002-03-29	src/screen.c
	* Changed setup screen stuff to be more generic (to make it easier
	  to add more setup screens).

2002-03-23	src/main.c, src/main.h
	* Various changes due to the introduction of the new libgame files
	  "setup.c" and "joystick.c".

2002-03-23	src/files.c
	* Generic parts of "src/files.c" (mainly setup and level directory
	  stuff) moved to new libgame file "src/libgame/setup.c".

2002-03-23	src/joystick.c
	* File "src/joystick.c" moved to libgame source tree, with
	  correspondig changes.

2002-03-22	src/screens.c
	* "HandleChooseLevel()": Another bug in level series navigation fixed.
	  (Wrong level series information displayed when entering main group.)

2002-03-22	src/editor.c
	* Slight change to support new gadget event "GD_EVENT_INFO_LEAVING".

2002-03-22	src/editor.c
	* Changed behaviour of "Escape" key in level editor to be more
	  intuitive: When in "Element Properties" or "Level Info" mode,
	  return to "Drawing Mode" instead of leaving the level editor.

2002-03-21	src/game.c, src/editor.c, src/files.c
	* 2.0.1 introduced the corrected "Emerald Mine" style behaviour of
	  gems (emeralds, diamonds, ...) slipping down from normal wall,
	  steel wall and growing wall (as in E.M.C. style levels). Although
	  the behaviour of contributed and private levels wasn't changed (due
	  to the use of "level.game_version"; see previous entry), editing
	  those levels will (of course) change the behaviour accordingly.

	  This change seems a bit too hard after thinking about it, because
	  the EM style behaviour is not the "expected" behaviour (gems would
	  normally only slip down from "rounded" walls). Therefore this was
	  now changed to an element property for gem style elements, with the
	  default setting "off" (which means: no special EM style behaviour).
	  To fix older converted levels, this flag is set to "on" for pre-2.0
	  levels that are neither contributed nor private levels.

2002-03-20	src/files.h
	* Corrected settings for "level.game_version" depending of level type.
	  (Contributed and private levels always get played with game engine
	  version they were created with, while converted levels always get
	  played with the most recent version of the game engine, to let new
	  corrections of the emulation behaviour take effect.)

2002-03-20	src/main.h
	* Added "#include <time.h>". This seems to be needed by "tape.c" for
	  compiling the SDL version on some systems.
	  Thanks to the several people who pointed this out.

2002-03-19
	* Version number set to 2.0.2.

2002-03-19
	* Version 2.0.1 released.

2002-03-18	src/screens.c
	* "HandleChooseLevel()": Small bug in level series navigation fixed.

2002-03-18	src/files.c [src/libgame/misc.c]
	* Moved some common functions from src/files.c to src/libgame/misc.c.

2002-03-18	src/files.c [src/libgame/misc.c]
	* Changed permissions for new directories and saved files (especially
	  score files) according to suggestions of Debian users and mantainers.
	  Thanks to Drew Parsons <dparsons@emerall.com> for the patch.

2002-03-17	src/files.c
	* Changed "{Load|Save}{Level|Tape}()" to IFF style file format:
	  Replaced "cookie" header string ("ROCKSNDIAMONDS_...\n") with
	  real IFF style header "RND1....XXXX" (where "XXXX" is "CAVE"
	  for levels and "TAPE" for tapes). Old "cookie" style format is
	  still supported for reading. New level and tape files are written
	  in new format.

	* New IFF chunk "VERS" contains version numbers for file and game
	  (where "game version" is the version of the program that wrote the
	  file, and "file version" is a version number to distinguish files
	  with different format, for example after adding new features).

2002-03-15	src/screen.c
	* "DrawHallOfFame()": "FadeSounds()" when entering the hall of fame.
	  (Before, you heard a mixture of the in-game music and the
	  hall-of-fame music.)

2002-03-14	src/events.c
	* Function "DumpTape()" (files.c) now available by pressing 't' from
	  main menu (when in DEBUG mode).

2002-03-14	src/game.c
	* "GameWon()": When game was won playing a tape, now there is no delay
	  raising the score and no corresponding sound is played.

2002-03-14	src/files.c
	* Changed "LoadTape()" for real chunk support and also adjusted
	  "SaveTape()" accordingly.

2002-03-14	src/game.c, src/tape.c, src/files.c
	* Important changes to tape format: The old tape format stored all
	  actions with a real effect with a corresponding delay between the
	  stored actions. This had some major disadvantages (for example,
	  push delays had to be ignored, pressing a button for some seconds
	  mutated to several single button presses because of the non-action
	  delays between two action frames etc.). The new tape format just
	  stupidly records all device actions and replays them later. I really
	  don't know why I haven't solved it that way before?! Old-style tapes
	  (with tape file version less than 2.0) get converted to the new
	  format on-the-fly when loading and can therefore still be played;
	  only some minor parts of the old-style tape handling code was needed.
	  (A perfect conversion is not possible, because there is information
	  missing about the device actions between two action frames.)

2002-03-14	src/files.c
	* New function "DumpTape()" to dump the contents of the current tape
	  in a human readable format.

2002-03-14	src/game.c
	* Small tape bug fixed: When automatically advancing to next level
	  after a game was won, the tape from the previous level still was
	  loaded as a tape for the new level.

2002-03-14	src/tape.c
	* Small graphical bug fixed: When pressing ""Record" or "Play" on
	  tape, cartoons did not get completely removed because
	  StopAnimation() was not called.

2002-03-13	src/files.c
	* Changed "LoadLevel()" and "SaveLevel()" to add new chunk "CNT2".
	  Fixed bug of "CONT" and "BODY" (chunk size was set to 8-bit element
	  size even when using 16-bit elements). Added new chunk "CNT2" for
	  16-bit amoeba content (previously written in 8-bit field in "HEAD"
	  chunk even when content was 16-bit element). "CNT2" should now be
	  able to store content for arbitrary elements (up to eight blocks of
	  3 x 3 element arrays). All "CNT2" elements will always be stored as
	  16-bit elements. "CONT" (with 8/16-bit elements) now obsolete.

2002-03-13	src/files.c
	* Changed "LoadLevel()" for real chunk support.

2002-03-12	src/game.c
	* Fixed problem (introduced after 2.0.0 release) with penguins
	  not getting killed by enemies

2002-02-24	src/game.c, src/main.h
	* Added "player->is_moving"; now "player->last_move_dir" does
	  not contain any information if the player is just moving at
	  the moment or not.
	  Before, "player->last_move_dir" was misused for this purpose
	  for  the robot stuff (robots don't kill players when they are
	  moving). But setting "player->last_move_dir" to MV_NO_MOVING
	  broke tapes when walking through pipes!
	  ("IS_MOVING()" uses "MovPos[][]", but this fails when it is 0
	  in a continuous movement. This fact is ignored for friends and
	  enemies, though.)
