Log Message:
-----------
Render Branch:
* Forgot to mention this in last commit. Currently image loading will look
  for an .tx file next to the specified image file, and if it exists, use
  that instead automatically. It compares the dates and always used the newest
  of the two.
* Fix uv y derivative being scaled wrong.
* Fix for possible use of invalid mipmap level -1.
