📄 Description

Adds the ability to emulate motion control inputs via a mouse. Since a gyroscope is a three-dimensional sensor, while a mouse is only two-dimensional, the full range of controls is achieved by having a (rebindable) toggle key to switch the behaviour of moving the mouse sideways between panning and rolling. While this is active, acceleration is spoofed to a constant downwards direction.

To enable it, press F6. You can also seamlessly switch between joystick and gyro emulation, if you select one while the other is active, it will cleanly switch modes, and if you press the toggle for the currently active mode, it will turn off.

The name for the keybind that switches between panning and rolling is mouse_gyro_roll_mode.

This is only the backend code and since this seems to be true for almost every PR I make, I think it will stay that way and I will pass off integrating it into the frontend to someone else.

Since it's using the same setup as joystick emulation, this is also conflicting with gyro data coming from a connected controller the same way joystick data does.

I only tested it with Gravity Rush 2, so further testing is very welcome.
