[Papervision3D] Tiles + Isometry Repost

[Jon Bradley]

Actually it's both a camera and an isometric draw function you'd need.

A separate draw routine would be in order for an isometric view so  
that you can efficiently draw the scene without perspective  
calculations. In this setup, you need a special orthographic camera  
and a separate draw routine that is used when this orthographic  
camera is the current view active.

By having the camera superclass, implementing an orthographic camera  
should be relatively easy. It's the render function that'll take a  
bit of effort. The math is much easier and faster for an isometric  
render.

 From a standpoint of whether or not it should be done in PV3D, I  
think the support should be there. Orthographic cameras are very  
useful and definitely have their place. If we build a full modeling  
application with PV3D, we need the orthographic camera in there. :)

Pauilus - maybe this is something you can try to tackle - implement  
an isometric draw routine and an orthographic camera.

Any thoughts?
