A cumbersome problem..... when constructing compound objects analytically, to keep
track of displacing surfaces to avoid coincidences tends to really obfuscate the code.
I suppose a general addition of a random offset would be simple enough, but then the
threshold of coincidence is sufficiently large that this wouldn't be reliable.
