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 git-svn-id: https://svn.eduke32.com/eduke32@4498 1a8010ca-5511-0410-912e-c29ae57300e0
