The problem is a trick that works in the original Doom.
The window is a zero-height sector with no textures
assigned to the surrounding lines.

Note to self:
This issue is now "half" fixed.

The remaining glitch is a product of the same issue as with
bug #743780.

Once detection is rationalized, reintroduce missing texture
replacement in such a way that all wall seg related
rendering algorithms respond to any changes - without
changing the "offical" textures on the sidedef.

Dani, this looks ok in 1.9.0beta4 (see attached screenshot).
Is this bug fixed ?

No not completely. This particular variation on this trick
is fixed but there is another similar trick that is setup
differently in the map geometry that I will be able to fix
using a method based on this. So, I left this open to remind
me :)

Ok. I had some spare time to triage bugs, so I though I'd
double check it. I'll reassign it to the current release as
it is still affected (and it means I won't forget I checked it)

We are almost ready to begin supporting these tricks.

I've been in discussions with Ajapted (of glBSP) who has provided me with a document detailing how glBSP reacts to these tricks and what it will produce in GL Nodes. I've also constructed a map containing examples of every DOOM.exe renderer trick I have come across to use for development with some fairly detailed notes to accompany it (covering common variations and screenshots of what the trick looks like in DOOM.exe). I plan to add the information to the DEW when made legible :-)

The map load algorithms have been enhanced so that some of the advanced tricks will no longer prevent the map from being loaded in Doomsday.

I plan to work on support for these tricks post 1.9.0-beta6

just a note to say as of deng 1.9beta-6.9 this bug still exists
