Nirbheek Chauhan f12ef34410 compositor: Actually use the output resolution for clamping ... The obscured check in compositor was using the dimensions of the pad to clamp the h/w of the pad instead of the output resolution, and was doing an incorrect calculation to do so. Fix that by simplifying the whole calculation by using corner coordinates. Also add a test for this bug which fell through the cracks, and just skip all the obscured tests if the pad's alpha is 0.0. https://bugzilla.gnome.org/show_bug.cgi?id=754107		2015-08-26 15:03:05 +03:00
