projection paint code can also do this, but not actually paint by hand
ofcourse, just use it to bake the image back.

The advantage with this is low res view project into high res texture
will work fine (wont miss pixels). and there is already code to do the
normal falloff (fade out faces that point away) and deal with UV bleed
