Effects collide with ground in some cases

[MrAntares]

Some effects collide with the ground, while they shouldn't This is either a zIndex/angle issue, or depth testing has to be disabled on effects.

This needs some more testing on official client. An easy test scenario: cast bash/soul breaker/meteor assault/heal/bless/agiup/sight behind a wall and see if they show through the wall. If so, then they have depth testing disabled.
