- MP3/OGG files are now decoded with dr_mp3 and stb_vorbis via the new
MakoMusic backend.
- Merge src/win/mako.cpp into src/generic/mako.cpp: Windows now uses the
same SDL audio path.
- A single SDL2 audio device mixes FM, BGM and PCM in its callback with
SDL_MixAudioFormat.
- PCM plays through SDL_AudioStream.
- dr_mp3 and stb_vorbis are vendored under deps/ and included from
mako_music.cpp. Warnings for that translation unit are silenced.
This adds support for "real" FM sound that can be used instead of MIDI
sound. (Currently only available on platforms where SDL_mixer is used.)
The MakoFM class interprets AMUS.DAT to create a write sequence to the
OPNA registers, from which fmgen generates an audio stream.
