Log Message:
-----------
Tweaked rendering inside a volume to always return alpha 1.0.
This fixes an issue which darkened the render from inside a
volume with sky or premul on. Still need to find a good way to
get an alpha value back into the shader (for compositing etc)
without getting the render distorted by premul.
