* Optimise them even further... AGAIN! Using an offset-based system rather than a multiplication-based one...
* Again, tweak the spawning code to take maximum advantage of these gains. * Fix potential crashes with MT_NULL mace/chain types supplied. * #ifdef out the height-clipping code. It needs more TLC than I can give it right now, and the existing behaviour is less obviously broken (sadly enough). * Fix chainmace points, which were apparently broken without anyone realising.
