Subject: [PATCH 2/2]DIX/ConfineTo: Don't bother about the bounding box when grabbing a shaped window
Patch-mainline: to be upstreamed
Git-commit: 3f7cc03e47a35d05ffb3f7a6de521c41638b4c7a

References: bnc#62146
Signed-off-by: Egbert Eich <eich@suse.com>

Limiting the the cursor coordinates on the bounding box of a shaped
window before applying ConfineTo leads to strange cursor placement
when the pointer is located outside  the vertial and horizontal
strip of this bounding box.
Ignoring the bounding box when a shape is set leads to the correct
behavior.
