Sounds very interesting although creating three separate functions for
specifying a vector is quite complicated and ugly for the user.  As
discussed in the function warp thread i think using vector functions -
although those can only be created using the average pigment trick or
Chris Huff's G patch right now - are probably a better solution.

Another possible use would be the 'multiple views in one image' scene. 
Therefore the possibility to specify the other camera parameters with
functions too would also be useful.
