Fixed bug #292 I might be on crack here. It looks like SDL_ConvertMono() in src/audio/SDL_audiocvt.c adds the left and right channels of a stereo stream together, and clamps the new mono channel if it would overflow. Shouldn't it be dividing by 2 to average the two sample points instead of clamping? Otherwise the mono sample point's volume doubles in the conversion. This would also make the conversion faster, as it replaces two branches per sample frame with a bitwise shift. --ryan.

6 The system window manager event contains a pointer to system-specific information about unknown window manager events\&. If you enable this event using \fI\fBSDL_EventState()\fP\fR, it will be generated whenever unhandled events are received from the window manager\&. This can be used, for example, to implement cut-and-paste in your application\&.

14 If you want to obtain system-specific information about the window manager, you can fill the version member of a \fBSDL_SysWMinfo\fR structure (details can be found in \fBSDL_syswm\&.h\fP, which must be included) using the \fBSDL_VERSION()\fP macro found in \fBSDL_version\&.h\fP, and pass it to the function:
