Fixed crash - need to save and restore rbx around cpuid, since the compiler may be assuming the stack pointer isn't being modified when filling in %0. I did it around each call to cpuid which isn't strictly necessary, but is definitely future proof. :)

SDL_CreateYUVOverlay \- Create a YUV video overlay
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"

\fBSDL_Overlay *\fBSDL_CreateYUVOverlay\fP\fR(\fBint width, int height, Uint32 format, SDL_Surface *display\fR);
.SH "DESCRIPTION"
.PP
\fBSDL_CreateYUVOverlay\fP creates a YUV overlay of the specified \fBwidth\fR, \fBheight\fR and \fBformat\fR (see \fI\fBSDL_Overlay\fR\fR for a list of available formats), for the provided \fBdisplay\fR\&. A \fI\fBSDL_Overlay\fR\fR structure is returned\&.
.PP
The term \&'overlay\&' is a misnomer since, unless the overlay is created in hardware, the contents for the display surface underneath the area where the overlay is shown will be overwritten when the overlay is displayed\&.
