bounce with slopes and a TERRAIN lump

[simc]

There's a strange(?) viewpoint bounce with slopes and a TERRAIN lump.

If there's a footclip value for deep water effect and the defined flat continues from a normal plane floor to a sloped downhill, the border of those sectors kind of bounces the players viewpoint up to the normal level.

Here's a short example wad. With idmypos I can see that the player's actual z-height on top of the bounce is 1 unit lower than on the plane floor.

This is one of the things that's unfortunately not fixable with Doom's screwed up physics code. More precisely, the way slopes are implemented makes any boundaries of such sectors one big messy problem that's basically unsolvable. I'm afraid there's nothing I can do here.
