24 Enables the use of asynchronous to the display surface\&. This will usually slow down blitting on single CPU machines, but may provide a speed increase on SMP systems\&.

27 Normally, if a video surface of the requested depth (\fBbpp\fR) is not available, SDL will emulate one with a shadow surface\&. Passing \fBSDL_ANYFORMAT\fP prevents this and causes SDL to use the video surface, regardless of its depth\&.

33 Enable double buffering; only valid with SDL_HWSURFACE\&. Calling \fI\fBSDL_Flip\fP\fR will flip the buffers and update the screen\&. If double buffering could not be enabled then \fBSDL_Flip\fP will just perform a \fI\fBSDL_UpdateRect\fP\fR on the entire screen\&.
