I'm using a flat panel screen now. I've noticed a big difference when the
images are displayed on a crt screen. I'll have to play with my gamma
steeings for the next render.

There are actually 316 individual isosurfaces that have been tiled. Each
isosurface has been optimised for its container (just big enough), its
max_gradient (exact) and its accuracy (based upon distance from the
camera).

I've written a series of pre parsing macros that do all the hard work. On
tests it looks like I've picked up about a 40-50% speed increase on a
single optimised isosurface when using the atmospheric media and radiosity.
