Compound Lens Simulator

Description of implementation approach and comments

I made an effort to take this one step at a time, so I wouldn't run into big problems with no idea what to fix.

My first step was to setup the rendering system, and make sure I get thr raster->camera and camera->world coordinate transformations correct. I tested this by setting the direction vector normal to the film plane (ie: (0,0,1) in camera coords.), and let everything run, which should produce a very small orthonormal projection. This is what I got:
