Great work, Bill! It has been some (too long) time since I last used 
meshrelief. This looks like a most interesting update indeed, just in 
time for my birthday. :-)

I posted my updates of lawnmaker and cloud shells to p.b.utilities, 
which seemed most appropriate, but it looks like p.b.scene-files is also 
a correct location after all.
