pfLight is a libpr immediate mode/pfDispList creature.
In 1.0/1.1, the only way to get a light in the scene was to
call pfLightOn with the proper xform on the stack, typically
in a callback.

pfLightSource is a new 1.2 inhabitant of a libpf scene graph. It
lets you just say 'I want a light there (XYZ in world coordinates)'.
Much easier.
