What does fillPercent actually do?

I've never actually been able to figure out what it actually does. Does it affect the amount of light that can get through the cell? Or the shadow height of the building? O.o

I know it stops projectiles if its a full cell.

It's how much cover it provides in a firefight, e.g. fillage 0.6 means it blocks 60% of projectiles.
