Hello,

  I would like to have a pfLightSource and switch it on/off
for different parts of the scene via draw callbacks. The man
page for pfLight says the pfLightOn depends on the current
transformation matrices. Is this the same for a pfLightSource ?
If so, what's the efficient way to go about this?

By the way, I know I can put pfLights in a pfGeoState. I do not
want to do this.

Thanks in advance,
