I just had an inspiration that perhaps the difference may
be that the GeometryArray has no colors array with the
ConstantMaps, but alas it does have a colors array and its
the same length as with the ScalarMaps to RGB (12 in both
cases, which is 4 vertices times 3 for R, G & B but no
alpha). However, I still think the key to finding a work-
around is finding the difference between these two cases
of Curtis's modification of your test program.
