Dynamic Light polys rotated to match THING/Wall angle
When using lightmaps there are many instances where
the top and bottom dynamic light polys should be
rotated based on the angle of the THING they are
attached to. For instance a lamp casting light in only
And for decor lights rotating them based on the angle of
the parent wall.
This rotation should be interpolated if the smooth actor
rotation is used.
Could this be made optional with a flag in the light def?
