Adam Strzelecki to SDL Since current DirectFB implementation is incomplete for YUV surfaces (actually causes segmentation faults when trying Lock and use YUV planar textures) I decided to fix it a bit. Here's a patch that should make DirectFB properly support YUV both packed and planar (3 planes). (1) Removed SDL_BYTESPERPIXEL at all in favor of DFB_BYTES_PER_PIXEL(SDLToDFBPixelFormat(fmt)) which does return always proper BPP for YUVs too, coz SDL_BYTESPERPIXEL returns incorrect values for FOURCCs (2) Fixed data->pixels allocation for planar YUVs in CreateTexture, it should allocate 150% more space (3) Copy other planes for planar YUVs in UpdateTexture (4) Moved checking if format is supported at all with DirectFB on CreateTexture at the beginning of the code Waiting for comments, -- Adam Strzelecki | nanoant.com

.SH "DESCRIPTION"
.PP
Pumps the event loop, gathering events from the input devices\&.
.PP
\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\&.
