  22 /* TODO list :
  23  *      - handling of palettes
  24  *      - recording (which input devices ?), a cam recorder ?
  25  *      - lots of messages still need to be handled (cf FIXME)
  26  *      - synchronization between audio and video (especially for interleaved
  27  *        files)
  28  *      - robustness when reading file can be enhanced
  29  *      - reimplement the AVI handling part with avifile DLL because
  30  *        "open @1122334 type avivideo alias a" expects an AVIFile/Stream
  31  *        and MCI_DGV_SET|STATUS_SPEED maps to Rate/Scale
  32  *      - some files appear to have more than one audio stream (we only play the
  33  *        first one)
  34  *      - some files contain an index of audio/video frame. Better use it,
  35  *        instead of rebuilding it (AVIFile does that already)
  36  *      - stopping while playing a file with sound blocks until all buffered
  37  *        audio is played... still should be stopped ASAP
