Made some improvements to the point density texture.  Added support
for tweaking the falloff with a custom curve.  Also coded new
falloff types based on the age or velocity of particles.

Also added a test break check to the volumetric shade cache code,
to avoid nasty hangups from the preview render (on render, exit,
etc).
