b28: Strange tile rendering near border of maps

[evouga]

If you go to the south or east border of a level, a few pixels of random tiles are rendered past the end of the level (as if the level extended further with random tiles). This effect is very noticeable in the Old Forest. The same glitch also occasionally occurs when fast-travelling (shift+dir): random tiles appear briefly as you're moving.

I got this weird sliver-of-a-tile border problem too, border is made from a sliver of whatever tileset the level uses. Been in since b27 for me I think.

I've seen this happening since B26.
