Beam parallel
This scripted entity is designed to make the input beams parallel to themselves at the output.
The entity will be turned on whenever the input beam hits it. If there is no beam present, this means the input beam is not in sync with the surface normal vector of the dimmer. If the vectors are in sync when the input beam hits the proper surface of the dimmer entity.
The output beam behavior and visuals ( texture, sounds, color, flags, etc. ) will be taken from the beam source entity from the current hit report. The dimmer can process many beams at the same time.
This entity has only one input, which is the normal local surface vector, and some outputs for information.
