TL;DR
Shadows shouldn't fall on top of lit up lamps.What ?
Shadows currently fall on top of lit up lamps. This is physically weird and looks ugly:The lighting effects should be rendered on top of the shadows. Not under them. It's obvious why this is just wrong.
Why ?
This looks even worse when you zoom out and aliasing effects make "shadows on top" look even worse:As a result, any attempt to make a graphical display made up of lamps looks significantly worse due to the compounded effects of all the wire shadows falling on top of the lighting effects. When fully-zoomed out, this effect compounds to looking like a "dimmer lamp".
