vQuake (Work in progress vid #2) with Dosbox-Rendition and RReady Rendition Verité @4k

V_FIFO_QSPANs appear to be rendering correctly now except for the texture clampjng (textures not repeating along the polygon). Polygonal content like enemies don't appear to be rendering anymore correctly. Underwater sequences don't appear to render either. The slowdown is because of debug logging.
The watermark logo is also missing in action. It looks like some elements are drawn to the wrong buffer (not the back buffer), either that or it's an z-buffering issue. Needs more investigating.
