Subject: [SDL] SDL_GL_GetAttribute( SDL_GL_MULTISAMPLESAMPLES ...
It would be nice to add the following lines:
case SDL_GL_MULTISAMPLEBUFFERS:
*value = 0;
break;
case SDL_GL_MULTISAMPLESAMPLES:
*value = 1;
break;
in wincommon\SDL_wingl.c int the function WIN_GL_GetAttribute at line
484, so that it returns the correct values when arb_pixel_format is not
supported.

| 3 SDL_SetColorKey\- Sets the color key (transparent pixel) in a blittable surface and RLE acceleration\&. | |
| 4 .SH "SYNOPSIS" | |
| 5 .PP | |
| 6 \fB#include "SDL\&.h" | |
| 7 .sp | |
| 8 \fBint \fBSDL_SetColorKey\fP\fR(\fBSDL_Surface *surface, Uint32 flag, Uint32 key\fR); | |
| 9 .SH "DESCRIPTION" | |
| 10 .PP | |
| 11 Sets the color key (transparent pixel) in a blittable surface and enables or disables RLE blit acceleration\&. | |
| 12 .PP | |
| 13 RLE acceleration can substantially speed up blitting of images with large horizontal runs of transparent pixels (i\&.e\&., pixels that match the \fBkey\fR value)\&. The \fBkey\fR must be of the same pixel format as the \fBsurface\fR, \fI\fBSDL_MapRGB\fP\fR is often useful for obtaining an acceptable value\&. | |
| 14 .PP | |
| 15 If \fBflag\fR is \fBSDL_SRCCOLORKEY\fP then \fBkey\fR is the transparent pixel value in the source image of a blit\&. | |
| 16 .PP | |
| 17 If \fBflag\fR is OR\&'d with \fBSDL_RLEACCEL\fP then the surface will be draw using RLE acceleration when drawn with \fISDL_BlitSurface\fR\&. The surface will actually be encoded for RLE acceleration the first time \fISDL_BlitSurface\fR or \fISDL_DisplayFormat\fR is called on the surface\&. | |
| 18 .PP | |
| 19 If \fBflag\fR is 0, this function clears any current color key\&. | |
| 20 .SH "RETURN VALUE" | |
| 21 .PP | |
| 22 This function returns \fB0\fR, or \fB-1\fR if there was an error\&. | |
| 23 .SH "SEE ALSO" | |
| 24 .PP | |
| 25 \fI\fBSDL_BlitSurface\fP\fR, \fI\fBSDL_DisplayFormat\fP\fR, \fI\fBSDL_MapRGB\fP\fR, \fI\fBSDL_SetAlpha\fP\fR | |
