SDL_DisplayYUVOverlay- Blit the overlay to the display
int SDL_DisplayYUVOverlay(SDL_Overlay *overlay, SDL_Rect *dstrect);
Blit the overlay to the surface specified when it was created. The SDL_Rect structure, dstrect, specifies the
position and size of the destination. If the dstrect is a larger or smaller than the overlay then the overlay
will be scaled, this is optimized for 2x scaling.
