By the protocol spec:
If a confine-to window is specified, then the pointer will be
restricted to stay contained in that window.
"Contained" is defined as:
A window "contains" the pointer if the window is viewable and the
hotspot of the cursor is within a visible region of the window or a
visible region of one of its inferiors. The border of the window is
included as part of the window for containment. The pointer is "in"
a window if the window contains the pointer but no inferior
contains the pointer.
The visible region must account for sibling clipping. borderSize is the
raw geometry of the window, whereas borderClip is borderSize clipped by
siblings.
