Subject: input: add a motion signal to weston_pointer
X-Git-Tag: 1.3.91~171
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6fcb378c016a7abc261da104f7bc3eb70e826b6b;p=platform%2Fupstream%2Fweston.git

input: add a motion signal to weston_pointer

The signal will be emitted after the pointer is moved. A shell plugin
can listen to the signal and activate certain effects when the pointer
touches the screen corners, for instance.
