Add a support to get a position of mouse cursor

Wayland lacks a feature to get a position of mouse cursor in multiple monitors.

This feature is very useful or important for many people who have different visual field defects/restrictions, they need the xeyes application to find a mouse in multiple monitors, but it works on Xorg only.

Can you maybe implement and offer the new feature like "How to get a mouse position and how to get a position of any app 'xeyes'" like wl_pointer.get_cursor() and something ? It would be nice to help people's eyes to find a mouse.

Thanks!
