Showing where PD can attack depending on terrain

@c-star Although theoretically possible, storing that information accurately enough (eg checking every 2x2 square) would require a large amount of memory, and take a long rime to load, on larger maps (eg 81kmx81km). The number of calculations would also vastly exceed the number required if a real time calculation was done, even if the calculations could be done upfront/spread out over the first 60s of gametime

would simple semi-transparent flat circle, rendered at the height of PD turret help?
it should clip under terrain in places where PD cannot shoot... this can help, however it does not guarantee anything at all...

maybe make pd spray fake projectiles (with same ballistic characteristics) and then you will for sure see areas where it can or can't hit (ray tracing lol, can reduce number of projectiles if performance is bad)... however no idea how that supposed to work if you move your mouse around a lot
