[sldev] Hide geometry in Sculpted-prims

[John Hurliman]

JPEG2000 supports an arbitrary number of channels/layers/whatever you want
to call them. In fact, avatar bakes are five channels (the last two are used
for bump-mapping and something else).

I agree though that you start to get diminishing returns from sculpties
pretty quickly. Take a 128x128 five layer sculpty vs. a decently robust
format built on top of a progressive meshing algorithm (
http://research.microsoft.com/en-us/um/people/hoppe/pm.pdf) and compare the
vertices per second, error curves, and total download sizes.
