It would realy be nice if this could be don in a more 'easy to 
understand' way. Something like:
camera {
    	loacation ...
    	look_at ...
    	lens_plane {rotate<..> translate<..>}
    	film_plane {translate<..>}
}

One problem with how it is done now is that the plane of focus is 
completly wrong is you use focal blur. Even nicer would it be if it 
followd the rules of 'Scheimpflug' and 'Hinge' 
http://fox.nstn.ca/~hmmerk/HMArtls.html to get the right 'plane' of 
focus.

http://www.benderphoto.com/8x10.htm it may look 'old-style' but mine 
has been working perfectly for the last 15 years.
