[Raypp-general] Updates

[Martin R. <martin@MPA-Garching.MPG.DE>]

Hi all,

I committed the new bifstream/bofstream classes and the new 3DS reading function
which uses them.
Next in my tree would be the activation of the triangle mesh (i.e. inclusion
into ray++.c and creation of the teapot executable.
Then I'd like to commit the RPN calculator which can be used to create generic
textures. This was already in my own CVS, but after 0.4 was released.
After that I'll think a bit about 2D and 3D Bresenham DDAs, because we will
certainly need them for height field traversals and probably also for octtree-like
bouding hierarchies (which may also be interesting for the triangle meshes).

Cheers,
   Martin
