Improve usage of window rectangles
* Skips non-AA diff rect elements and replaces them with window
rectangles.
* Places window rectangles in the interiors of antialiased diff rects.
* Arranges two overlapping window rectangles in a plus shape inside of
diff rounded rects.
* Enables window rectangles when clearing and generating clip masks.
GTX 960 perf result (with vs. without window rectangles):
