Log Message:
-----------
had it in mind for years now to record a matrix above all primitives (akin to
putting each primitive into their own comb) so that all primitives will retain
a local coordinate system by default (where their V stays at 0,0,0). this will
help primitives like the torus support non-uniform scaling without screwing
with the implicit form of a torus.
