The attached file shows that the distribution of the triangles of the
patch is not even. It also shows how to create the triangles with a
double loop as an alternative to the subdivision approach.

Yet another version. Added uv-mapping and now holds the 'normalisation 
property'.

Yet another version. I made the distribution of the triangles even and
made the code generate a mesh2 instead of mesh, which saves
calculations. I also did a few other optimizations.

I have removed UV mapping for now, since linear UV mapping probably
won't be of much use anyway. I'm looking into non-linear UV mapping.

By the way Micha, could you set up the editor you use to create spaces
instead of real tabs? I think that's the common standard.
