Game controller support Initial game controller support. Actions are based on the Switch branch but the controller code itself is implemented differently, allowing for easy remapping and minimizing changes to the Source/ directory. Many subtle and not so subtle controller bugs have been fixed in this implementation, including: 1. Smoother & more responsive movement with the joysticks. 2. Consistent controls for all the menus in the game (stores, quest log, etc). 3. Cursor appearance / disappearance at appropriate times. Low-level controls are abstracted and 3 SDL interfaces are supported: game controller, joystick, and keyboard. See SourceX/controls/ for more details on this. Wishlist for the future: 1. Primary button and use button should attack continously. This is hard as it requires checking the cooldowns / attack speed. 2. Quick spell menu navigation is very buggy. It is also buggy in the switch branch. I haven't had a change to investigate.
