[Bf-python] BMesh upgrade docs & api info

[benoit.muller at laposte.net]

Hi,
thank you for this usefull document.

I'm currently upgrading my Exporter to 2.63 and I have 2 questions. I would be 
gratefull if someone could help.

1) I cannot find the UV information on the MeshTexturePoly. Where should be the UV 
information when using NGons (Mesh.polygons).

2) The 3DEngine supports Tris and Quads, and is performant with quad.
So my plan is to first iterate on all Ngons of the Mesh. 
If max NGons are <=4, I would use Mesh.polygons to export Tris and Quads
If max NGons are >4, I would use Mesh.tessfaces to export tesslated Tris.
Is it a good strategy ?


Regards,
Benoit Muller
