[Bf-python] Texture API- first "sketch"

[alex mole]

Hi

I'm creating the Texture.py docfile first, as it should provide a good 
description of the Texture API. I've epydoc'd it and put it here:

http://www.geocities.com/lordbosh/Texture/

This first sketch should give an idea of what I'm aiming at. There are 
still several other classes I need to plan: MTex, EnvMap and ColorBand.
Also, the Texture class is missing any reference to the flags, imaflags 
and stype fields of the Blender Tex struct. This is because I am waiting 
on your advice [see my earlier post ;)] before I decide how to implement 
these.

As well as creating this new module, I plan on adding the following 
functions to Material.Material:

getTextures()- returns the 8 texture channels as an 8-tuple with None
                for empty channels and Texture objects in the rest

setTexture(num,tex)- set channel _num_ to texture _tex_

clearTexture(num)- remove a texture from channel _num_

To replicate Blender's internals perfectly, the above functions should 
deal with MTex structures linked to Texture objects. However, I think 
that there should also be versions to deal with Texture objects 
directly, as these will probably be needed more often. Perhaps variants 
getMTextures() and setMTexture(num,mtex) could be supplied for dealing 
with MTex objects?



Let me know what you think!

[BTW, some parts of this are already implemented. If anyone wants to 
play with them, I can send you a diff or something....]
