A feature that automatically scales the UVs of the flats (okay well maybe not "UV"; I don't know what is it internally, but I hope you understand) so that when the sector is sloped, there would be no texture distortion.
I'm sure everyone knows what will happen when you extremely slope a sector; the texture will look really stretched and distorted. So this feature is about drawing the texture at a 1:1 scale no matter how "sloped" the terrain is.
Not sure how would this be implemented. MAPINFO? Custom field in the sector? A new arg for the slope line specials or things?
