Using clear avoids the shader engine (see last commit), so if we can get pixels out of it, we should. So we detect the overlap with the rounded corners of the clip region and emit shaders for those, but then use Clear() for the rest. With this in place, widget-factory on my integrated Intel TigerLake gets a 60% performance boost.
