Trust me, we're not to the point where a client-side function call per 
polygon is a performance issue.  Note that because Render pre-composes the 
trapezoids to avoid rendering errors along edges, even a hypothetical 
multi-polygon API would still need to generate multiple protocol requests.

You don't.  Use XRenderChangePicture with a clip_mask of None.  This 
parallels the Xlib routines for the core protocol.
