No whatnsew: Really, really, really fixed the remaining pixel alignment and UV clamping issues. Tested Gradius, Pac-Man, Mr. Do, and Stompin' with no observed issues. Gradius, in particular, is a good test case as the bottom row of its "Credits" readout lies on the bottom row of pixels, and the scrolling starfield allows visual verification of the X extents as they scroll on and off.
