I just had a look at the 3.1/megapov source and found there is some change
in megapov supplying new interpolation routines, but it isn't activated
(HField->smooth_type is always 1)

The normal calculation code seems fairly understandable although i don't
have time to check it right now.

BTW, i wonder how much slower it would be not to store the normals and
calculate them from the vertices during trace.  This could save a lot of
space when dealing with large heightfields.
