From Bug #36: There are a couple of issues with the selection of Altivec alpha-blitting routines in CalculateAlphaBlit() in src/video/SDL_Blit_A.c. 1) There's no check for the presence of Altivec when checking if the Blit32to565PixelAlphaAltivec() routine can be selected. 2) Altivec cannot be used in video memory, and there's no check if the destination surface is a hardware surface. (Alpha-blitting to a hardware surface with GPU support is a bad idea, but somebody's bound to do it anyway.) Patch to fix these attached.

13 \fBSDL_PumpEvents\fP gathers all the pending input information from devices and places it on the event queue\&. Without calls to \fBSDL_PumpEvents\fP no events would ever be placed on the queue\&. Often calls the need for \fBSDL_PumpEvents\fP is hidden from the user since \fI\fBSDL_PollEvent\fP\fR and \fI\fBSDL_WaitEvent\fP\fR implicitly call \fBSDL_PumpEvents\fP\&. However, if you are not polling or waiting for events (e\&.g\&. your filtering them), then you must call \fBSDL_PumpEvents\fP to force an event queue update\&.
