Changes in 1.0.0
- (devel) Detect UPX, fix some race issues in the Makefile, disable
  optimization if GCC 4.5.0 is detected (to work around an optimization bug),
  fix version.h generation if there is a version.h in /usr/include.
- (devel) Fix a number of compiler warnings.
- Clamp the arguments for -w and -h to 65535 as that is the maximum size of a
  PCX.
- Fix reading of PCX files with more bytes per scanline than pixels.
  (This is the case for odd image widths when following the PCX standard closely.)
- Silence progress-meter output when stdout is not a console.
- Unify warnings and errors so they go to stderr and are prefixed by "Warning:"
  or "Error:".
- Allow hex escapes that have bit 31 set.
- After cropping a sprite, compress and write the correct number of bytes.
- Add -X to print PCX sprite numbers in hex
- (devel) Many compilation issues with different compilers and architectures.
- Fix bug in UTF-8 generation for escapes \U800..\U7FFF.
- Fix U+E0xx characters being output quoted.
- (devel) By Tron: code cleanup, make C functions and variables static where
  possible, remove dead and debugging code.
- Require two slashes before dismissing anything as a C++ style comment.
- Fix reading of real sprites with Unixy absolute paths.
- Check for pixels with palette index of 255 when encoding.
- Add -q to silence warnings.
- Add -c to automatically crop extraenous transparent blue pixels.
- Add escapes for the new action 2 operations 0E, 0F, 11, 12, 13, 14, 15, 16
- Prevent quotes and escapes in sprite 0.
- Add escapes for long-format intro dates.

Changes in 0.9.10 (r819)
- (bugfix) Correct reading of \7c, \7C, \D| and \D&. (DaleStan)

Changes in 0.9.9 (r653)
- By Patchman:
  - Check for sprites that extend beyond the end of the PCX file.
  - Update versioning system to show last-comitted revision for non-release
    builds.
- By DaleStan:
  - (devel) Add release targets to the Makefiles
  - Check the palette of the PCX file before encoding from it.
    (Override a failed check with -f)
  - Introduce several backslash escape sequences; see the wiki for further
    information.
    (disable with -x or -xx)
  - Do not apply colormap to sprites that like character glyphs.
    (Apply colormap to all sprites with -M instead of -m)
  - Enable reading of GIMP palette files with -p.
  - (devel) Terse build mode; get the verbose mode with make V=1.
  - (devel) Touch version.h if and only if it changes.

Changes in 0.9.8 (r197)
- By DaleStan:
  - (devel) grfcodec (but not grfdiff or grfmerge) can now be built in
    MS Visual Studio 2003.
  - Slightly change the plaintext quoting algorithm.
  - (devel) Change several memcpy()s to pointer assignments.
  - (devel) Plug several memory leaks
  - (devel) Source code and Makefile changes to grfdiff and grfmerge build
    with both Makefiles, on both Cygwin and Linux.
  - Make code gcc 4 -Wall clean.
  - Use NFORenum's NFO reading engine:
    - Sprite numbers are now optional, and need not be correct if present.
    - Sprite lengths need not be correct. Set to 0 to supress the incorrect
      length warnings.
    - Real sprites are checked for format compliance.
  - Make 0-byte pseudo sprites an error.
  - (bugfix) Prevent binary includes from including directories on OSes that
    would othewise allow it.
  - (bugfix) It is now possible for a real sprite to start above the
    preceeding sprite (the infamous decreasing ypos bug)
  - grfcodec now exits with 0 on success.

Changes in 0.9.7
- support including binary files using "  4 ** data/dingdong.wav" syntax
- by Oskar: support // and # comments within pseudo-sprites
- fixed incorrect error message while encoding if .nfo file could not be read
  (now it reports "Cannot read %s" instead of Creating sprites/: File exists")
- made code -Wall clean
- remove myalloc stuff

Changes in 0.9.6
- by pasky:
  * made it possible to compile grfcodec on Linux
  * made compatible with gcc 3.x
  * when decoding, text strings are written in plain text (disable with -t)
  * supports plain text in .nfo files
  * fixed bug when first encoding a grf file wouldn't rename .new to .grf

Changes in 0.9.5
- self-extracting executables now work on Win2K etc., which doesn't pass
  the full path to the C library
- GRFMerge will just skip .grf files it can't find
- making sprites larger doesn't work if they're at the right edge; complains
  that ofsx too large; instead just use background colour
- GRFDiff doesn't like grfdiff -l 1254 ... (single value in -l), complains
  that there were no differences and makes no output
- allow GRFMerge to read GRFDiff's .exe files, both for -l and other options

Changes in 0.9.4
- fixed yet another crash while compressing
- sprites no longer need correct numbers in the .NFO file; just use "-1" for
  each number and it will be assumed to be correct

Changes in 0.9.3
- fixed crash due to buffer overrun while compressing
- slightly improved compression efficiency and speed
- GRFCodec now handles spaces in file/directory names properly
- GRFCodec now supports comments in .NFO files (from //, ; or # to end of line)
- speed up PCX processing

Changes in 0.9.2
- fixed crash if pcx file not found
- fixed crash if nfo file has no version info header

Changes in 0.9.1
- bug fix by Marcin: wrong order of test in encode function

Changes in release April 20 2002
- -p now actually uses the parameter you give it

Changes in release Dec 03 2001
- made -p option a valid option
- improve compression speed even more using assembly optimizations
- compression is now on by default, disable with -c-
- fixed bug where encoding would fail if the grf file didn't exist already
- fixed bug where decoding would fail creating the sprites directory
- corrected some mistakes in grf.txt (checksum, and initial offsets for tiles)

Changes in release March 26 2001
- fix bug that didn't flush last row if it only contained a single sprite
- fix bug with no height given (would make PCX have height -1)
- show percentage done while decoding
- fix compression algorithm
- improve compression performance
- try without compression if data is inconsistent after decompressing our
  compressed data (this shouldn't happen anymore anyway, report it as a
  bug if it does)
- -p to choose palette

Changes before release March 26 2001
- I don't remember anymore
