    The question on the floor:  is there a better way than Unmapping and reMapping
    to get a transparent window's background corrected after it has been moved?

I should have amended: X10 transparent windows were used primarily for
two distinct purposes: one was as a rectangular clipping region for
output, and the other was for cursor/input control.  In X11, GCs
provide for general clipping, and InputOnly windows provide for
cursor/input control.
