Copy the code for stretch_blit and remove the x logic.

For raycaster (one of the two users):

  • -2 ms on 32blit
  • -6 ms on PicoSystem
  • -27 ms (ish) on PicoVision (drawing vertically is still bad for perf)

A lot of the improvements can also be gained by replacing the contents of stretch_blit_vspan with stretch_blit(src, {uv, Size{1, sc}}, {p, Size{1, dc}});. Probably because I already optimised that a lot.

Oh, PicoSystem number may be slightly off as I'm running from the PicoVision branch with it's hacked down clock. It's definitely still an improvement though.
