	Some cool *old* MegaPov feature :) In MegaPov 0.7, there is
the sample_spacing keyword which can increase the number of samples
taken depending on the distance the light travels in the media. The
result is a fast media where it can and a slow media where it must,
with near constant quality.

	The other solution is as you said to break up the sky into
several objects, or to add transparent planes to force povray to take
more samples. Both those solution will require increasing the
max_trace_level, which could have big consequences if you have complex
glass objects in your scene...

	Of course, those methods only work with media based clouds :)
