Fixed fonts so they render (mostly, still have original problem with mimapping example)
Fixed font display (and likely other issues related to the same problem). Problem was due to the foolish assumption I made that if the same pointer to a texture was sent to SetTexture again then the actual texture was still the same.
Fixed the same error as last commit in other places.
Basic fixed function 3D working (Aaaa is the only thing it works with at the moment). Produces issues with the esc menu in Aaaaa and flickering score text.
