When we were shaping the window with a cairo region, there was an easy optimization to restrict painting only to the pixels we were going to actually draw. With rounded corners, the amount of work we have to do figure out what pixels isn't worth the small savings of not drawing the completely transparent parts of the corners, so remove this optimization, and the supporting meta_shaped_texture_get_visible_pixels_region() https://bugzilla.gnome.org/show_bug.cgi?id=657639
