The angle value is also used in later code, the create_ray() function in 
render.c for example. I suggest you look at the camera parsing code in 
parse.c for an example.
I can't really help you more without knowing what you are attempting to 
do.

These are for focal blurring, I assume.

This tells what kind of camera it is, perspective, orthographic, 
fisheye, etc.

This is simply the camera normal.
