Summary	0000314: Sides with negative scale are misaligned
Description	On C1M5 in WolfenDoom: Blade of Agony, the door near (X: 2030, Y: 560, Z: 24) is misaligned if you use the g2.4-pre-529-304e989 build, but it is not misaligned if you use the g2.4-pre-310-gbecc00a build. My best guess is that the issue is caused by the negative scale on the front sidedef of that line.
Steps To Reproduce	Load up WolfenDoom: Blade of Agony Go to C1M5 Enter the catacombs and go to the resistance hideout.
Additional Information	I have not been able to see whether this issue occurs on a more recent build, since it seems the more recent builds have trouble parsing USDF.
Tags	No tags attached.

This was a discrepancy between the OpenGL and the software renderer. This should be fixed in the maps, because reverting this change will bring back the other problem.
