As far as I can figure, there's no way to represent near and far clipping 
planes in a transformation matrix, right? The camera itself (in some sense) 
has to carry them along separately?  I.e., the near and far clipping planes 
don't get represented anywhere in a normal 4x4 transformation matrix?

   Forget "focus follows mouse." When do
   I get "focus follows gaze"?
