Description
A canvas window is a geometry manager, too.
The window geometry code is skipped, if it is not
a direct child of that canvas.
Side note there are no bindings processed for
windows. This is because these bindings can't
be used anyway -- all events are dispatched to the
window -- this is no oversight!
