Game Engine UI: Image Sampling Texture Panel cleanup

removing non-GE supported features.

The idea of splitting the draw() function comes from Campbell Barton.
Review from him as well.

The main reason for not implement this in properties_games.py is to make sure the
panel is in the same order for both BI and BGE engines.
