Actually, this is a better fix...clear the error state once if everything we need loaded; it's more efficient, and works even if the last unnecessary xrandr symbol failed to load. Otherwise, leave the original loadso error, so the end user can find out what symbol failed.

.SH "NAME"
SDL_CreateRGBSurfaceFrom\- Create an SDL_Surface from pixel data
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBSDL_Surface *\fBSDL_CreateRGBSurfaceFrom\fP\fR(\fBvoid *pixels, int width, int height, int depth, int pitch, Uint32 Rmask, Uint32 Gmask, Uint32 Bmask, Uint32 Amask\fR);
.SH "DESCRIPTION"
.PP
Creates an SDL_Surface from the provided pixel data\&.
.PP
The data stored in \fBpixels\fR is assumed to be of the \fBdepth\fR specified in the parameter list\&. The pixel data is not copied into the \fBSDL_Surface\fR structure so it should not be freed until the surface has been freed with a called to \fISDL_FreeSurface\fR\&. \fBpitch\fR is the length of each scanline in bytes\&. 
.PP
See \fI\fBSDL_CreateRGBSurface\fP\fR for a more detailed description of the other parameters\&.
.SH "RETURN VALUE"
.PP
Returns the created surface, or \fBNULL\fR upon error\&.
