[sldev] Google Summer of Code 2008 update

[Gary Wardell]

Well, it is a little odd to be in a cave or enclosed skybox with no visible source of light and yet there is light that seems to
change with the day/night settings.

While it's not all that inconceivable that there is some general illumination (just like on Star Trek or Dr Who all the aliens
speak English)  it would be even worse if there was a visible shadow in such enclosed spaces that indicating a pin point light
source that isn't there.
