Solved the performance problems by introducing the concept of a single-buffered display, which is a fast path used for the whole-surface SDL 1.2 API. Solved the flicker problems by implementing a backbuffer in the GDI renderer. Unfortunately, now using the GDI renderer with a backbuffer and HBITMAPs is significantly slower than SDL's surface code. *sigh*

.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\&.
