Having a child/subwindow and knowing the top-most
ancestor window id (under the root window but not 
including the root), how can I find the top-most
window's width and height?

The only information I have on the child window
is its drawable area, not the rest of the window
structure.  And all I know about the top level
window is its id.

Is there a simple solution?

I tried cheating by adding fields to the drawable
structure, but this blew up things using the shape
extensions.
