Swimming out of water
If you are fast enough you can jump out of water by swimming up.
In original game you can't cross water level by swimming up. You must get to surface, levitate or cast water-walking spell.
At water level there is switching between swimming and running animation. Speed of animation switching depends mostly on player speed attribute.
Howto reproduce: Jump into water. player->SetSpeed 300 player->SetAthletics 100 player->SetStrength 100 player->SetAcrobatics 100 Swim up.
Note that Speed=300 can be obtained eg. with Boots of Blinding Speed.
