Henrik Rydgård 169f473b95 Smart 2D texture filtering: Use the new vertex path to check for pixel mapping in transformed geometry 
Previously, "Smart 2D texture filtering" was limited to through-mode
draws, but many games use fully transformed draws to do 2D elements.

An example of this is Outrun in the menus, and it's always been plagued by
horrible filtering artifacts.

With the improved Smart 2D texture filtering, the artifacts are gone!
Of course, instead of glitchy bilinear you instead get point sampled
texturing so it looks more pixellated, but no more ugly borders between letters
in the game.
