Slightly more on topic, why does POV consider a light_source to be a 'patch
object' in the following code, when it complains about 'cannot invert a patch
object'?  Because it just happens to be lumped with the list of things that
don't have inverses, which happen to mostly be patches?
// POV warns about 'cannot invert a patch object' on the second line.
#declare ls = light_source {<2,3,4>,rgb 1}
object {ls inverse}
