MAP29 Compatibility Fix

[Hellser]

This is for Map29 of Doom 2. It fixes the missing texture issues with the teleporters in the main room. With OpenGL, it looks like crap. Software, still looks like crap. Now it looks better. The texture is taken from the FRONT side (which is not seen) under any normal conditions. Safe to say Romero wanted to use this texture for the backside, but forgot to set it or did not notice.

With OpenGL, it looks like crap.

That doesn't seem right. Shouldn't the OpenGL renderer at least look like software with missing lower and upper textures?

That should probably be reported as a bug. I don't know if it can be fixed, though.

Nevertheless, outside the scope of this thread, which I've gone ahead and closed and marked as added.

The OpenGL effect is a result of how it treats untextured holes. Unlike the software renderer, you can look directly downward into it. That means that doing simple texture bleeding is not sufficient to completely fill the hole with the flat texture and the renderer treats any hole with no textures on any side so that its surface gets rendered with the bleeding flat texture. In some extreme cases like this one it may not do what's desirable but the opposite effect would create a lot more problems overall (i.e. break pretty much any intentional case of omitting the lower wall textures.)
