Update:
-made rog almost twice as fast as it was before. For example, in de_mon, it took 207ms to generate all the points, now it takes 100ms.
-previously it was 4.3x faster than superspawn, now it is 7.8x faster than SS.
-it generates the same amount of points, but in half the time it took before.

-added a check to prevent spawn points on top of entities(this should filter boxes like the ones from dust2 bombsite).
-added the same check that is used in regamedll for steep surfaces. If the ground is too step and the player would start sliding down, then that point will not be taken into account.

I have more updates planned, which should hopefully filter even more tricky points(like spawning in places that are too high).
