Subject: Force pointer to stay on screen.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=90e701df0898538ca06ad4327697a4e55644b4d4;p=platform%2Fupstream%2Fweston.git

Force pointer to stay on screen.

Without this change it's really easy to
accidentally send the pointer flying and not
be able to get it back.
