[PATCH 25/51] drm/i915: Implement proper clipping for video sprites

2012-10-25 Thread ville.syrj...@linux.intel.com
From: Ville Syrj?l? Properly clip the source when the destination gets clipped by the pipe dimensions. Sadly the video sprite hardware is rather limited so it can't do proper sub-pixel postitioning. Resort to a best effort approach, where the source coordinates are rounded to the nearest (macro)
