Glowing texture for projectile option

As it says in the title, a simple option/checkbox to apply a glow texture/layer to a projectile's texture, seeing as projectiles are entities. (I'm guessing this is possible but I don't know, but all the forum topics on 'glowing projectiles' are just people asking if it's possible from a couple years ago.) Hoping this gets added as a feature, it would be very useful to implement things like lasers :^)
