Sprites that are affected by the angle of dynamic lights

[ThatKidBobo]

When something is in front of a light source, it will look darker, since you will see the face that does not get any light.

This is not the case in Gzdoom, actors react to light without keeping the angle they are facing in mind.

What I am requesting here is: If an actor's front is facing a light source, render the actor's back darker, and fade to the front's light level when rotating around the actor.

Would this look werid, and is it possible to do? If it is possible, will you consider adding something like this? Perhaps make it optional?
