[gzdoom-g2.1.pre-385] UDMF texture scale bug
Looks like UDMF vertical texture scaling is broken when negative scale is used.

Re: [gzdoom-g2.1.pre-385] UDMF texture scale bug
Fixed. This was a simple case of badly applied texture clamping. For negative scales the texture ended up in texture coordinate range [-1..0] where only [0..1] would work. The code to correct this was already there for camera textures (which are created upside down due to OpenGL's nature) but was missing for normal ones.
