Hi Tim, I just don't understand why Texture2D isn't sufficient for everything you are doing. glTextureRectangle is deprecated, it was a temporary workaround added to OpenGL, you shouldn't need it at all now that OpenGL fully support non power of two textures.
So please just use Texture2D all the way. Robert.
