The server uses pWin->origin to compute screen coordinates from window
coordinates. Use of this for the root window is fairly limited, but not
non-existent.

I like the idea of reporting the global system geometry to clients
though; perhaps just an XFixes extension request that returns the whole
array? Less stylish, but also respects the current semantics.
