(*
The ice gun has the following effects:
A "ray" like a deagle is projected out from the gun.
All these effects assume the ray's angle is not changed and that the target type was unchanged over a number of ticks. This is a simplifying assumption for "gun was applying freezing effect to the same target".
* When fired at water a layer of ice textured land is added above the water.
* When fired at non-ice land (land and lfLandMask and not lfIce) the land is overlaid with a thin layer of ice textured land around that point (say, 1 or 2px into land, 1px above). For attractiveness, a slope would probably be needed.
* When fired at a hog (land and $00FF <> 0), while the hog is targetted, the hog's state is set to frozen.
As long as the gun is on the hog, a frozen hog sprite creeps up from the feet to the head.
If the effect is interrupted before reaching the top, the freezing state is cleared.
A frozen hog will animate differently.
Frozen hogs take less damage and are harder to push.
This might make freezing potentially useful for friendlies in a bad position.
A frozen hog stays frozen for a certain number of turns.
Each turn the frozen overlay becomes fainter, until it fades and the hog animates normally again.
