The first thing would probably to contact the TAG about that, they can
forward your suggestions. Anyway, it probably will not be included in
Povray 3.5 so it could be a better idea to incorporate it into a version
of megapov based on 3.5.
Concerning the idea itself, as someone already mentioned, single precision
is not much faster than double (although memory use is lower of course)
and therefore it would be only much difference if it used new features
like 3D!Now which would be problematic for portability reasons.
