I'm not sure what you're asking. If the window is not
visible, it has an empty cliplist. There is simply nothing
to draw.

There is a "PanoramiXScreenRegion" in the server. It doesn't look
like it's used for anything and is just leftover from DEC's original
implementation (I guess I should remove it).
XineramaScreenRegions are the parts of the desktop that each
individual screen takes up. This is really only used in GetImage
calculations.
