Duke3D: Jumping out of TROR water is somewhat broken
If the distance between a TROR water surface and the ceiling above (either a normal sector ceiling or another transparent TROR layer) is less or equal to 18432 units, then the player is completely unable to jump out of the water, despite there being visibly enough room to do so. In fact, the player has no problems jumping out of a regular water sector in the same situation.
This issue dates back as far as r3078, and as such I suspect it has been an issue as long as TROR water has been a feature.
Attached are a number of test maps that demonstrate odd TROR water behavior, test map 02 and 03 are relevant in this case. By dropping into the pool, the player becomes trapped, despite normally being able to jump out just fine.
