Feature Request: Accelerometer Mouse Control

The software gamepad is challenging to use in some situation where you need fast precise movement.

My suggestion is a setting to use the accellerometer to control the phone accelerometer to make mouse movements. The obvious use case would be aiming in games. Some games like PUBG and also the steam deck use this style of aiming and it is a big improvement from simply using a software thumbsticks.

I think this would be fairly simple to implement and would make gaming with moonlight without a gamepad much more feasible and enjoyable with certain games. This would have the added benefit of letting your rest your hands on the action buttons without having to swap between right joystick and right trigger constantly with your thumb which is very slow and difficult to do precisely.

A couple suggestions which may or may not be necessary: a menu option to control sensitivity within moonlight so it can be configured seperately from default mouse/joystick speed. An optional software gamepad button that can be used to toggle accelerometer control in case leaving it on causes some mouse conflicts.

The issue does not name any files, tests, or entry points. Start by locating the Android software gamepad handling and accelerometer sensor integration, then determine how sensitivity and an optional toggle should fit the requested behavior. Done means accelerometer movement can control the mouse reliably without disrupting existing gamepad controls.
