Each triangle of a quad has its own UV planes, which a sprite built from the corners doesn't reproduce. Textured triangle rectangles now only become sprites in through mode with nearest filtering. Gears of Destiny's text boxes become bit exact against the PSP, and no dump compared gets worse. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
