Well, I was going to draw more attention to it once this had to be
integrated into the visualization pipeline. Basically, the new code
works directly on k3d mesh arrays, supports subdivision of only part
of a mesh, skips faces with holes and handles named array data. It is
also designed to run in parallel, with future porting to CUDA in mind.

It's not much work to use this to replace the old library, so I have
already moved the code to k3dsdk/subdivision_surface. I have left the
handling of the painter caches unchanged, all that is needed is a
small refactoring of the visitors that are used, this is already done
for the SDS face painter.

Cheers,
