January 4, 2009 (Changes by Graf Zahl)
- added GZDoom's 3D floor physics code. This is not active yet so anything
compiled from this code won't have any support for it!
- Used new functionality to avoid moving the puff around in SpawnDeepSplash.
- Fixed: P_RailAttack used the shooting actor or a default puff for some splash
related actions. It should use the puff type passed to it as a parameter instead.
