Would it always slow down the filter, or only if these expressions are 
actually a function of time?
Some nice effects would be possible when the angles and/or field of view 
could be functions of time.
A "eval" option (like in "eq" filter) could be added to specify when to 
evaluate the expressions, and the default would be "init" for fast
