This isn't quite right, actually. This solution would only work if the difference clip geometry is a rectangle and the the CTM is scale-only. Both of which are true in the case we're hoping to optimize for. Some more elbow grease is needed to form a proper solution. |

Culls more aggressively for cases where a difference clip intersects with the current clip coverage rect such that the coverage boundaries become smaller.
This may help reduce redundant rendering work in cases where there's a full screen platform view in the scene.
