Can you use temp vars to give these rects names, similar to
checkerboard_draw_quad.cc? Also, I think the opaque rect should be empty until
you have something visible in the quad in the future with some data to make that
decision on. (These won't be 100% opaque given you can have transparent
renderers.)
