This effectively makes MetaShapedTexture not a MetaShapedTexture, but a simple and dumb MetaMaskedTexture, with an optimization for clipped regions. We're doing this as the mask may need to be more complicated than made of a cairo path -- we eventually want GTK+ to draw the entire frame background, which we'll then scan. https://bugzilla.gnome.org/show_bug.cgi?id=676052
