SkyratBot 0b65cc596b [MIRROR] Overlay lighting component (#469)
* Overlay lighting component (#52413)

Sparks no longer lag, projectile beams move super smoothly, same with mobs and whatnot. This also allows for easy expansion into directional lights, field-of-view, wee-woo rotating lights or whatever.

It does have a downside: things right-clicked or checked through the alt+click tab will show the light overlay:


This is a BYOND limitation, very well worth it IMO.

🆑
add: Smooth movable lighting system implemented. Projectiles, sparks, thrown flashlights or moving mobs with lights should be much smoother and less laggy.
balance: Light sources no longer stack in range, though they still do in intensity.
