ApplyTexturing's per-pixel path built each pixel's color from four strided channel values, which the compiler stored in pieces and then loaded as a vector, a store forwarding stall per pixel. On x86 and ARM64, where the sampler takes its color in a register, the channel rows are transposed in registers instead, and back afterwards.

To get to 100% compatibility, we will need a software renderer as there are games out there that do tricks that can't really be faked in a sensible way. Useful for homebrew too that mix sw and accel rendering.
