Differentiate Multiple Mice On Same Computer

[cheesyface1]

Is your feature request related to a problem?

I am using Steam Remote Play and would like the ability to address the local mouse and remote player's mouse separately. Currently, if two people (local/local or local/remote) each have their own mouse, it is a "shared mouse" and either player can move the shared cursor at any time, even if it is the other player's turn. Which, of course, causes problems.

Contrast this behavior where both players have a gamepad or one player uses the mouse/keyboard and the other player uses a gamepad (each player's device can be addressed individually without affecting the other device).

I think a LOT of people would find their games a lot easier to use with Steam's Remote Play function if there was the ability to let both the local/remote player use their local mouse.

Describe the solution you'd like

I would like to be able to address multiple mice (and even multiple keyboards) individually sort of like the way gamepads are addressed.

For example:

• Getting mouse 1's x position could be: mouse_x(1)
• Getting mouse 2's x position could be: mouse_x(2)

Describe alternatives you've considered

• YellowAfterlife's Raw Input
• Designing my game around a shared-mouse scenario. (Works, but it causes problems.)

Additional context

This feature request seems to be conflating two different things:

• Distinguishing multiple locally-attached physical mouse devices
• Distinguishing Steam Remote Play mouse input from local mouse input, which according to this post from YellowAfterlife on the GMC forum is not presented to the OS like a separate device
