pump this through a client-side library to convert it for them. configuring
this is fairly complex with the different demands for different clients and
the differing capabilities of the gamepad hardware.

assuming we have two clients C1, C2, and C1 has the gamepad open, what is
the behaviour of the gamepad and the shared pointer:

- when the gp-controlled pointer enters/leaves C1's surface
- when the gp-controlled pointer enters and clicks inside the surface
- when the compositor changes the keyboard and/or gamepad focus to C1's
  surface while the gp-controlled pointer is inside or outside the surface,
  respectively
- when the mouse-controlled pointer enters and/or clicks C1's surface
- when the mouse-controlled pointer leaves the surface while a gamepad
  button is held down
  - when the gamepad presses a button after the mouse-controlled pointer has
    left the surface
- if a keyboard event triggers a compositor shortcut immediately followed by
  a gamepad button event (e.g. alt-tab followed by gamepad button 1 press,
  does this select the window currently underneath the pointer?)
- what is the position of the cursor between the gamepad detached and
  reattached to pointer mode
