Capture/release window in DX9 implementation

Browse Source 
This helps a lot when the user drags a slider but carries the cursor offscreen before releasing the button - without the capturing, the slider will "stick" to the mouse cursor even after the button has been released. (This should generally be added to all Windows implementations - I won't mind doing it if you think it's a good idea.)
