[Papervision3D] Smart Textures

[Ralph Hauwert]

Arne,

You are spot on 100%. We didn't do this flag wise, and won't do that.
Instead, we now have smart materials. This is how the new textures and
shaders will work in RC2, and this is exactly how you will be enabled
to write your own materials. You will be provided with vertex normals
(optional, if needed only and you will be able to set on what nTh
frame they will be updated...this is a performance optimisation), face
normals (they will just always be there), and the screenZ etc.

Gouraud and Z are there, as are phong and bumpmapping, toonrendering
and mipmapping (not working yet that one). My personal holy grail is
normal mapping, which will work, but I just need the time to finish it
: time is my main issue momentarily. As far as RC2, the ball is mostly
in my court in this moment.

Although the material API is mostly set, there's still work to be
done, and currently optimisations are my main point off interest. I
expect some major performance increasements, next to the ones we've
already achieved.
