Ok, problems. :(

To generate a unique cloud map for each planet, I need to (among other things)
load the image map and normal map.

From these, I need to take samples along the x and y axis, and I don't know how
to do so. My first thought was the trace() function, but I don't know whether I
can get trace() to return the colour of the intersection.

Second problem, even if I can use trace(), this means that I have to have the
colour_maps in the scene in some form or another, and as the cloud_map is
partially transparent, this would mean that the other objects would appear in
the final render. :(

Perhaps I could get around this by using two scene files? Downside would be less
convenience, but if it's the only way...
