(Very spotty) change log for tfmx-play

 + means feature added.
 * means bug squashed.
 - means feature removed.

Changes in tfmx-play 0.6
 * added patches for NetBSD (thanks to Thomas Klausner)

Changes in tfmx-play 0.5
 * fixed problem when writing to a file (thanks to Stefan Ohlsson)
 * fixed problem with Turrican 2 World 2 Song 0 and others (also thanks to
   Stefan Ohlsson)

Changes in tfmx-play 0.4
 + maximum pathname-length has been extended to 1023 bytes
 * fixed three buffer-overflows that could happen when pathnames
   longer than PATHNAME_LENGTH-1 bytes were used (strncpy is now used
   instead of strcpy)

Changes in tfmx-play 0.35
 * mono- and 8-bit modes were partially broken in ALSA-hack, fixed

Changes in tfmx-play 0.3
 + yesss! it finally works with the OSS-emulation layer of ALSA :)

Changes in tfmx-play 0.2
 + linear oversampling code contributed to tfmx-play

Changes in tfmx-play 0.17
 - Dumped realtime-scheduling, because it was too insecure and
   not really useful (on a P133 or faster machine "top" thinks the player
   process is idle, that should explain it).
 + Added "make install" rule to Makefile (path is user configurable).

Changes in tfmx-play 0.16
 * Stupid bugs in DmaOn/DmaOff commands which screwed up everything.
 * Fixed mixer to more accurately reflect Amiga behavior for WaitOnDma
   commands.
 + Since the above two bugs were fixed, we can sorta play older mods now!

Changes in tfmx-play 0.15
 + Takes advantage of sched_setscheduler to get real-time (available only
   with libc 5.3 and newer kernels) support.  This is an attempt to reduce
   the skipping that normally occurs when the system gets busy.

   Once enabled in the Makefile, it can be disabled with the -S option or by
   running it as someone other than root.  Note that the included executable
   _is_ built with real-time support and may (but shouldn't) cause problems
   on systems whose kernels do not support real-time scheduling.

   ALSO, please note that to use the real-time scheduling option, this
   program must be run as root.  !!!!DO NOT SET THIS PROGRAM UP AS SETUID
   ROOT!!!!.  It is trivial to create a "song" that copies bytes from
   a sample file (which could be linked to /etc/shadow!) directly to the
   output (which could be placed anywhere on the drive).  The next version
   _may_ drop privileges once the scheduler is set up, but this one does
   NOT.

Changes in tfmx-play 0.14
 * Stupid little problem with full stereo split mode (forgot to put in a
   for loop.  Geez....)
 + Added simple weighted-sum low-pass filtering.

Changes in tfmx-play 0.13
 ? Changed the sound handling massively.  Now allows the creation of lots of
   audio data (128k to be exact) and has a sort of FIFO ring for input and
   output.  Might help skipping a little bit.  Next task: making the create
   routine use smaller blocks than the play routine.
 + Try oversampling with the -v option and tell me how you hate it.  Note
   that it sucks big CPU power and only works well on a DX4/100 or better!
   (Actually, it's not _really_ oversampling; it's just 14-bit interpolation.
   It may spontaneously become proper oversampling as soon as I can get a
   good algorithm worked out.)

Changes in tfmx-play 0.12
 * Infinite loops containing finite loops.
 * Portamento might work this time =:^)
 + Added blend function (instead of -s for stereo, -b## for stereo blend, on
   a scale of 0=stereo to 128=mono.  Sounds great through headphones!)

Changes in tfmx-play 0.11

 + First real public release.
