[Bf-committers] Scripting Loop subdivision using the Mesh module

The current blender python api is very poor this
import/export/create meshes is ok but mesh editing is a pain, you need
to remove faces and add them back in again (in the case of subdivision
you need to add more verts too)
I did this a while ago and it works ok but its quite tedious and you
need to minimize how many times you extend and delete
faces/verts/edges or the script will get slow since it re-allocates
Hopefully the 2.5 api will allow better mesh editing within scripts
