scummvm/sound/mididrv.cpp
Torbjörn Andersson 13dc149ded Applied patch #1175374 ("FluidSynth MIDI driver"), with a few documentation
changes. There are a few things that could use a bit more work, and I've
only tested it on my Linux box. I have verified that ScummVM still compiles
when it's disabled, though, so it shouldn't break anything too badly.
