Version 2.0.2
   Additions/changes by Andrew J. Robinson:
      Tracking window.
      Use XtPopup/XtPopdown instead of XtMapWidget/XtUnmapWidget.
      Remove colors from fallback resources, and put them in an app-defaults
         file instead.
      Handle WM_DELETE_WINDOW - closing a window using the window manager will
         now close only the individual window, not the entire application.
      Lists don't show their name when they are empty
      Automatic detection of VoxKit driver version at run time.  The
         OLD_DRIVER compile option is no longer needed -- the binary will work
         with both driver versions (2.90-2 and 3.0+).
   Additions/changes by Alex Mohr:
      Patch for missing initialization of some variables.
      Patch to fix module lengths (currently in contrib/fix_length.patch)

      the man page for more info. 
   The file queue can be saved and loaded.
   The "Shuffle" button randomizes the play queue.
   "Random play" option plays modules in a random order.

   Pitch slides in S3M modules are affected by the base note of the sample.
   Temporarily disabled ULT tuning, since it is not handled correctly.

      in S3M modules.
   Changed valid note range for S3M modules.
   Shifted all MTM notes up one position (as they should be :-) ).

-------------------------------------------------------------------------------
Version 1.3 (Additions/changes by Andrew J. Robinson)
   Added support for "Set Finetune" command
   Modified effects slightly.
   Added "-r" option to infinitely repeat modules.  (suggested by Wayne Hodgen)

   Changed (NTSC) sample playing frequency from 8448 Hz to 8363 Hz.
   Initial S3M support.  There is currently VERY LITTLE error checking in
      the S3M loader, so it may crash.

   Display of current position number and pattern number.
-------------------------------------------------------------------------------
Version 1.2b (Additions/changes by Andrew J. Robinson)

      to load compressed modules. :-(
   Fixed a bug when there was tone portamento with a sample specified.
   Samples which do not completely load will no longer cause "short file"

   Recognition of "M!K!" signature.
   Different exit codes.  (also suggested by Zygo Blaxell)
   If all samples in a MOD file are empty, then gmod no longer tries to play
      it.  This will prevent gmod from trying to play some non-music files.

   Fixed a problem with the proper patch sometimes not being selected.
   Support for all standard 669 commands.
   Fixed initial panning for 669 modules.
   Recognition of "Extended 669" format, although extended commands
      are not yet supported.
   Modules compressed with 'compress' or 'gzip' can now be played.
-------------------------------------------------------------------------------
Version 1.1a (bug fix by Andrew J. Robinson)
   Fixed a bug with volume when notes were delayed or retriggered.
-------------------------------------------------------------------------------
Version 1.1
   Many thanks to Robert Sanders for his excellent MTM & ULT loaders, and his
      numerous great suggestions!

   Additions/changes by Andrew J. Robinson:
      8 channel module support.
      Period table extended to cover more octaves.
      Reduction in the number of global variables.
      Fixed 669 sample loading to load ALL samples.
      Changed read to fread, lseek to fseek, etc.
      Added support for log volume in UltraTracker version 1 files.
      Added support for the panning command.
      "Set Speed" command now converted to either "Set Ticks" or "Set BPM".
      Each note can now have two commands.
      Volume now ranges from 0 to 255.
   Additions/changes by Robert Sanders:
      GUS memory checks/memory reporting.
      MultiTracker (MTM) & UltraTracker (ULT) loaders.
      "Show empty samples" option.
-------------------------------------------------------------------------------
First numbered version!  (V1.0)  (Additions/bug fixes by Andrew J. Robinson)
   Made seqbuf_dump more persistent -- if the entire buffer isn't written to
   the queue, it will keep trying.
   Improved pitch slides -- they are now linear with respect to period
   rather than pitch.
   Added "FLT4" module support.
   Added the rest of MOD commands except "set finetune" and "invert loop".
   Added support for tuned samples.
   Fixed 669 playing -- 669 modules should now play correctly, but 669
   effects are not yet supported.
   Changed calculation of speed.  I hope it's right this time :-)
   Added a small calculation to attempt to minimize loop clicking.
-------------------------------------------------------------------------------
Release date:  23 Dec 1993 (Additions/bug fixes by Andrew J. Robinson)
   Added sync_time after initial set-up.  This may help cure a problem with
   pitch slides sometimes not working.
   Changed the way bad samples are handled.  Now, the channel is turned off
   if a note is played on that channel using a bad sample.
-------------------------------------------------------------------------------
Release date:  22 Dec 1993 (Additions/bug fixes by Andrew J. Robinson)
   Fixed a misplaced 'if' statement.
-------------------------------------------------------------------------------
Release date:  21 Dec 1993 (Additions/bug fixes by Andrew J. Robinson)

   Added support for arpeggio, tone portamento with vol slide, pattern loops,
   pattern delays, note cuts, note delays, and the "fine" commands.
   Corrected (hopefully) volume slides, pitch slides, and speed command.
   Added code to use "closest note" when period in MOD file does not match
   a period in the table.
   Added checks to reduce the number of MIDI events put in the queue.
   Miscellaneous other small fixes.

Notes:
   The pitch of a note cannot be slid beyond two octaves of its original
   position.  This is a limitation of the Linux sequencer drivers.
