[Bug 42358] Improve wine control game controllers with background pictures

https://bugs.winehq.org/show_bug.cgi?id=42358

--- Comment #5 from Bruno Jesus  ---
A gamepad is divided (generally) in axes and buttons.

The left analog stick handle the axes X/Y movement while the right analog stick
handle the axes rX/rY. In generic controllers the D-Pad (the four arrows for
left/up/right/down) are recognized as buttons, sometimes as what is called a
hat.

You can use jstest-gtk to remap the buttons/axes to whatever you want and that
will reflect in Wine.
