 Added byte-swapping input and output to rcalc.
 
 Additional error-checking for source surfaces.

+Re-fixed bug in octree code that caused it to allocate 8 times as
+much memory as it actually used(!) -- this was pointed out way back
+in 1999 by Erik Reinhard and Erik Jansen, but the fix they gave me
+got lost in the slightly borken release process at the time.  This

+Corrected ray weights for material mixtures.

+Reduced the default -n setting for obj2mesh to take better advantage
+of the smaller octree structure size.
