ambient lighting

Browse Source 
Summary:
Specific object to represent light which is 100% everywhere. Sometimes lighting is irrelevant, for example when viewing a mesh which has lighting already baked in.

This is not primarily aiming for a performance win but I think the test which has changed might be a bit faster.
