I do not know wether I'd classify this as a bug or a feature request, seing that there's a new lump (HIRESTEX) to support a new way of scaling, but it'd be nice to have the 0x8000 flag supported in Gzdoom 
The upper-mentioned 0x8000 is the flag that enables scaled textures, scaled with the texturex lump, to be offseted using map-units and not pixels. This is VERY handy for aligning hi-res textures (I tried DB and there's no problems).
I'm 100% sure Zdoom supports this (as I tested it and they come ouf fine). Gzdoom lacks it.
Can I kindly ask for it? Although I'm not developing for Gzdoom (I'm doing for Zdoom) I often test my map(s) to check my hi-res textures in the game, in Gzdoom to see how it looks in OGL.
EDIT: Zdoom 2.0.95 is my version.
