- To allow for XAudio2 to work properly, we need to rework how does provider work since they only are used to be able to take in mono audio.
- Other providers have been dumbed down to accept single channel audio since originally aegisub only accepted 1 channel audio.
- meson.build has been modified to accommodate for xaudio, as we currently don't accept redistributable forms of xaudio, we need to work around the WinNT version.
- There has been 1 more fix to res.rc to allow for compiling on non tagged releases.
Use std::chrono since it's a nicer API. Use a separate lock for playback
position so that the GUI thread isn't blocked for hundreds of ms while
snd_pcm_drain is waiting, and update the playback position after
decoding audio rather than before to avoid it being significantly wrong
when not using a cache.
