Render surface's owning layer should not generate quads with blend mode.
The root layer of a subtree that is render to a separate surface
doesn't need to use a blend mode for its draw quads.
GL renderer currently uses the blend mode only in DrawRPDQ, so it
shouldn't be affected by this change.
Software renderer uses blend mode for all kind of layers, but this patch
should not change the output pixels, since blending layers are always
promoted to render surfaces, and the first layer drawing to a clean
render surface will not be affected by the blend mode.
