Fixes from Dmitry Yakimov:
fixed bugs 159 and 160:
+ added threaded timers support
! fixed restoring sdl window focus (AV in windows message handler)
! disabled forgotten cdrom and joystick in config file.
* disabled minimizing sdl window while loosing focus.
PocketPC does not have a task bar, so it is an inconvenient and unusual
behaviour for PPC users.
+ added WIN_Paint handler for GAPI
! fixed loosing focus while using GAPI videi driver
+ added TestTimer project
* removed unnecessary macros (ENABLE_WINDIB ...) from projects

The \fBvolume\fR ranges from 0 to \fBSDL_MIX_MAXVOLUME\fP and should be set to the maximum value for full audio volume\&. Note this does not change hardware volume\&. This is provided for convenience -- you can mix your own audio data\&. .PP .RS \fBNote: .PP Do not use this function for mixing together more than two streams of sample data\&. The output from repeated application of this function may be distorted by clipping, because there is no accumulator with greater range than the input (not to mention this being an inefficient way of doing it)\&. Use mixing functions from SDL_mixer, OpenAL, or write your own mixer instead\&. .RE .SH "SEE ALSO" .PP \fI\fBSDL_OpenAudio\fP\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 22:58
