- // The root cause of this bug was that when dual source blending was not supported and we made a
- // copy of the destination to perform blending we would clip the copy bounds to the current clip.
- // However, it is possible for anti-aliased that are fully contained by the clip in a geometric
- // sense to actually draw outside the clip in pixel space because we don't consider aa bloat when
- // determining if the draw is contained by the clip.
