Cosa è cambiato in EDuke32, build per build

When that mode is enabled (see below for caveats), wall textures that have a non-power-of-two height (call it 'h') will be modified to look like in classic: Let 'H' be the next power of two greater than 'h'. The texture will be uploaded with height 'H', made up from 'h' hlines of the original texture, followed by 'H'-'h' first hlines of the same. No panning "corrections" will take place. The mode is disabled by default. Caveats/notes: * the mode requires that r_hightile is disabled * it is not implemented in Polymer * in the Lunatic build, it is ineffective when a VX map is loaded, as those display walls with NPOT height textures correctly

Specifically, the handling of one-way walls ([1] in Mapster32) was slightly different.

This mode does not take a sector's visibility values into account for uniform darkening of a texture. It is more faithful to classic with respect to fog/visibility *distances*, but may be less so as far as the "tint" of the texture due to visibility attenuation is concerned.

With this mode, the near distance of the linear fog is always 0, unlike being negative with r_usenewshading 2.
