Randy Heit 10c0d67b78 - Changed the MIDIStreamer to send the all notes off controller to each
channel when restarting the song, rather than emitting a single note off
  event which only has a 1 in 127 chance of being for a note that's playing
  on that channel. Then I decided it would probably be a good idea to reset
  all the controllers as well.
- Increasing the size of the internal Timidity stream buffer from 1/14 sec
  (copied from the OPL player) improved its sound dramatically, so apparently
  Timidity has issues with short stream buffers. It's now at 1/2 sec in
  length. However, there seems to be something weird going on with
  corazonazul_ff6boss.mid near the beginning where it stops and immediately
  restarts a guitar on the exact same note.
- Added a new sound debugging cvar: snd_drawoutput, which can show various
  oscilloscopes and spectrums.
- Internal TiMidity now plays music.
- Changed the progdir global variable into an FString.

This version of TiMidity should contain all the fixes from the
September 25 2003 SDL_mixer CVS snapshot, plus extended GUS patch
support from later SDL_mixer. In addition, it contains these changes
from SDL_sound:
* Removal of much unused or unnecessary code, such as
+ The "hooks" for putting a user interface onto TiMidity.
+ The antialias filter. It wasn't active, and even at 4 kHz I
couldn't hear any difference when activating it.
+ Removed all traces of LOOKUP_HACK and LOOKUP_INTERPOLATION.
According to the code comments they weren't very good anyway.
("degrades sound quality noticeably"). I also removed the
disclaimer about the "8-bit uLaw to 16-bit PCM and the 13-bit-PCM
to 8-bit uLaw tables" disclaimer, since I believe those were the
tables I removed.
+ Removed LOOKUP_SINE since it was already commented out. I think we
can count on our target audience having math co-processors
nowadays.
+ Removed USE_LDEXP since it wasn't being used and "it doesn't make
much of a difference either way".
+ Removed decompress hack from open_file() since it didn't look very
portable.
+ Removed heaps of unnecessary constants.
+ Removed unused functions.
+ Assume that LINEAR_INTERPOLATION is always used, so remove all
code dealing with it not being so. It's not that I think the
difference in audio quality is that great, but since it wouldn't
compile without code changes I assume no one's used it for quite
some time...
+ Assume PRECALC_LOOPS is always defined. Judging by the comments it
may not make much of a difference either way, so why maintain two
versions of the same code?
* Made TiMidity look for its configuration file in both /etc and
/usr/local/lib/timidity. (Windows version remains unchanged.)
* The following files have been removed: controls.c, controls.h,
filter.c, filter.h, sdl_a.c, sdl_c.c
* Added support for loading DLS format instruments:
Timidity_LoadDLS(), Timidity_FreeDLS(), Timidity_LoadDLSSong()
This version of TiMidity also contains my own changes for ZDoom:
* Removed readmidi.c: TiMidity is now fed MIDI events directly to
produce output. The TimidityMIDIDevice class is responsible for
feeding TiMidity data and collecting output from it. Since
ZDoom's MIDI parser ignores SysEx messages, so does this TiMidity,
though this can be changed if necessary.
* Removed all the precalculated math from tables.c in favor of using
real math functions.
* All sample values are now floats, and only a stereo 32-bit float
output buffer is supported.
* Moved everything into the Timidity namespace.
