I recently added a bunch of oddball video modes to my XF86Config, to support weird resolutions xine & mplayer need if I don't want to beat my cpu up with video scaling. Since adding them, SDL started picking the biggest video mode it could find that matched the height constraint. Getting a narrow vertical strip of QuakeForge (I code for the project, so needless to say it's my favorite test) in the middle of an 800x480 screen, instead of the 640x480 I asked for annoys me tremendously. So here's a patch that tries a bit harder to get an exact match. I didn't touch the XiG section, since I can't test that, but I'd bet a similar patch would prevent similar problems there. --Ragnvald "Despair" Maartmann-Moe IV

SDL_GetRGB\- Get RGB values from a pixel in the specified pixel format\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"

\fBvoid \fBSDL_GetRGB\fP\fR(\fBUint32 pixel, SDL_PixelFormat *fmt, Uint8 *r, Uint8 *g, Uint8 *b\fR);
.SH "DESCRIPTION"
.PP
Get RGB component values from a pixel stored in the specified pixel format\&.
.PP
This function uses the entire 8-bit [0\&.\&.255] range when converting color components from pixel formats with less than 8-bits per RGB component (e\&.g\&., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8])\&.
