Yes, that makes sense.

All your macro needs now is a way to set the relative scale, in case the rest of
the scene was not modeled with 1 pov-unit = 1mm. This would help a lot with
'dropping in' the macro to existing scenes that were not written with that in
mind. For example, many of the sample scenes that come with POV!

Something like Camera35mm_SetUnitsPerMM(0.1) or Camera35mm_SetMMPerUnit(10), for
a scene where 1 pov-unit = 1cm. I can't say I completely understand the lens
maths involved with your macro so I'm not sure how feasible this would be.

Anyway, thanks again for a really useful macro!
