--new script action: LightBackground. This lets you apply a global lighting filter to the background in a static cut scene. One parameter: Global Lighting Preset. If you leave this parameter blank (or use "Custom" for it), you can use optional second, third, and fourth parameters: Red, Green, and Blue values for custom lighting. This all works just the same as the Global Lighting condition.
LightBackground does nothing if used outside the context of a static cut scene with a -PIC:- present.
