Good point.
So, basically, waveOutGetID (and likely waveInGetID) need to explicitly special
case WAVE_MAPPER, instead of pushing it through WINMM_DecomposeHWAVE (cause
that one seems correct as it is).

Something like:

if (hWaveOut = WAVE_MAPPER) 
  *lpuDeviceID = WAVE_MAPPER;
else
  WINMM_DecomposeHWAVE((HWAVE)hWaveOut, lpuDeviceID, &is_out, &dev, &junk);

That way current WINMM_IsMapper check will make some sense.
