407   This material should be used sparingly, as it may cause the light
408   source calculation to blow up if it is applied to many small surfaces.

428   The prism1 material is for general light redirection from prismatic
429 < glazings, generating secondary light sources.
429 > glazings, generating virtual light sources.
430   It can only be used to modify a planar surface (i.e., a polygon or disk)
431   and should not result in either light concentration or scattering.
432   The new direction of the ray can be on either side of the material,
433   and the definitions must have the correct bidirectional properties
434 < to work properly with secondary light sources.
434 > to work properly with virtual light sources.
435   The arguments give the coefficient for the redirected light
436   and its direction.
