Blend TextureLayer background-color at draw time.
This enables the following optimization:
1. The compositor will be able to disable GL blending
if the background-color is opaque.
2. For elements that paint directly to a texture layer,
i.e. accelerated canvas, video, etc., there is no need to
allocate an additional layer just to paint the background.
