MaxED 0d90d9b297 Visual mode: regular walls are now clipped by solid 3d floors (this should eliminate z-fighting).
Fixed, WavefrontExporter: floor and ceiling textures were not exported when using "classic" game configurations (ones with disabled "MixTexturesAndFlats" option). This should also fix incorrect flats on exported model when there are flats and textures with the same name.
Fixed, WavefrontExporter: 3d floors geometry and wall geometry around them was created incorrectly.
Fixed, WavefrontExporter: floor and ceiling textures of non-Vavoom 3d floors were swapped on exported geometry.
