I don't expect that these problems will be fixed in time for the release,
given my current time constraints. If anyone else would like to take a 
look, as always they are very welcome to do so!

I think they are most apparent in stratus and nimbo-stratus layers, so
I suggest that we comment out those sections in cloudlayers.xml for the 
release. This will mean that those cloud types will be displayed as a 
2D layer.

I've been testing with this on my own system, and it resolves most of 
the issues, and looks acceptable for these cloud types.

Heiko - you have been working hard on the 3D cloud textures, so I'd like
to hear your opinion on this.
