- update to version 2.0.2
  * Add SDL2_mixer-only-load-required-interfaces.patch
    Prevents initializing decoders unnecessarily.
    Fixes an issue with applications that use the API incorrectly
    (due to misleading documentation).
  * Build with libmpg123 where available
  * Fix fluidsynth linking
  * 24-bit and surround sound support for FLAC audio files
  * Updated for SDL 2.0.6 and newer
  * Support for MP3 playback using mpg123
  * Added Mix_OpenAudioDevice() to specify the audio device to open
