public class PaintVolume
PaintVolume is an opaque structure whose members cannot be directly accessed.
A PaintVolume represents an a bounding volume whose internal representation isn't defined but can be set and queried
in terms of an axis aligned bounding box.
A PaintVolume for a Actor is defined to be relative from
the current actor modelview matrix.
Other internal representation and methods for describing the bounding volume may be added in the future.
