A device that reports an axis held from the start (a virtual pad nobody holds, a trigger or pedal mapped onto a stick,
a stick resting far off its middle) turned the camera or moved Link on its own, and since pad_active counted it as
pressed, it could take the gamepad role from the controller in the player's hands whenever that one was idle, and keep
it. input.c now reads every axis through pad_axis: 0 until the axis has been within a quarter of its range of rest
(a trigger's rest is 0), then the device's value. The game's sticks and triggers, the menu's stick readout and the
choice of gamepad all use it. A stick the player holds at the start counts once it has been let go.
Checked: the runtime compiles; new tests/pad_rest_check.py (pad_axis cut from input.c, SDL stood in for) passes: a
held axis reads 0 for 100 polls, a released one reads the device, and axes and gamepads keep separate states;
tests/mouse_stick_check.py still passes. Not run with a real device.
