It is, but I'm not sure it is working on the level of individual sprites. The
clouds are in the correct rendering bin (I think), but because of the use
of shaders we currently just render them in an arbitary order within each
cloud.
I wonder if the problem is the CouldShaderGeometry::drawImplementation().
Does that seem likely?
