#12 [2.1.0 Test-1] Floor/wall textures glitching

[Julian Nechaevsky]

Textures of floors and mid-walls are glitched in some upped floors.
In Vanilla logic, floor texture must not be drawn through middle-wall texture, and middle-wall texture must fill missing lower-wall texture.

Bug appears on both texture smoothing ON and OFF, and was found on MAP25, right in front of secret area behind bloodfall and also on MAP31 in front of cages.

Here's how it looks: https://youtu.be/fvPTG28Zx1U
