Partial gamepad for IronLynx/Maze4d

The joysticks are used for “normal” movement (as seen on the main cross-§). The direction pad is used for up/down & movement orthagonal to the main cross-§. The button pad is used for “abnormal” rotation, or rotation that doesn't “fit” in the main cross-§ (A/Y controlls a degree of rotational freedom; X/B controlls another). The trigger bumpers controll roll (on the main cross-§). The triggers controll an “abnormal” degree of rotational freedom (according to the main cross-§). IronLynx/Maze4d is available on GitHub; to apply this confuguration, IronLynx/Maze4d must be added to Steam as a non-Steam game (see the + button near the bottom corner of the library window).
