Gamepad support for free camera mode

[aybe]

Would it possible that you offer gamepad support for free camera mode ?

A 6DOF scheme like the following would be great:

• left thumbstick : strafe left/right, move forward/backward
• right thumbstick : look up/down/left/right
• A/B/X/Y buttons : move up/down, roll left/right

Thank you :+1:
