Good technique ... also, I've often found that I need screen-relative
coordinates when I'm parsing mouse movements.

In this case it's very simple: mouse events have x_root and y_root
fields which give the mouse position in absolute screen coordinates.
By subtracting the x, y fields, you can get the enclosing window
position.
