Enhanced scale up and scale down in SDL2. #210

The current SDL2 only scale up in full screen mode. This PR enhance the scale up in window mode. The user can change the scale factor at will by resizing the window.

When user restore the window from minimize or maximize, it restores the scale ratio to 1.
