// Class : OccluderEffect
// Description : This functions similarly to a LightAttrib or
// ClipPlaneAttrib. It indicates the set of occluders
// that modify the geometry at this level and below.
// Unlike a ClipPlaneAttrib, an OccluderEffect takes
// effect immediately when it is encountered during
// traversal, and thus can only add occluders; it may
// not remove them.
