-look at clipList, and that no other fields from the
-window will be used. it's not possible to just draw
-in the root because it may be a different depth.
-
-to get the tile to align correctly we set the GC's tile origin to
-be the (x,y) of the window's upper left corner, after which we
-get the right bits when drawing into the root.
