[feat] Monitor::from_point and Monitor::cursor_position

[OceanBelongsToMe]

Describe the bug

I have two available monitor, and I want to display the window on the current display，but the window.current_monitor() method does not seem to return the display screen where the mouse is located
It seems that the form always appears in the main display！
this is my code：

#[tauri::command]
fn register(app_handle: AppHandle, window: Window) {
  app_handle
    .global_shortcut_manager()
    .register("CTRL + U", move || {
      if window.is_visible().unwrap() {
        window.hide().unwrap();
      } else {
        println!("New version available: {:?}", window.available_monitors());
        window.center().unwrap();
        window.show().unwrap();
        window.set_focus().unwrap();
      }
    })
    .unwrap();
}

Additional context

this is my monitors

Ok([Monitor { name: Some("Monitor #41012"), size: PhysicalSize { width: 2880, height: 1800 }, position: PhysicalPosition { x: 0, y: 0 }, scale_factor: 2.0 }, Monitor { name: Some("Monitor #30471"), size: PhysicalSize { width: 3840, height: 2160 }, position: PhysicalPosition { x: 0, y: -2160 }, scale_factor: 2.0 }])

The current_monitor API returns the monitor on which the window currently resides. It has nothing to do with where the mouse is located.

[OceanBelongsToMe]

Yeah, I looked at the api again, it is indeed the monitor where the form is returned, so there is no api that can return the position of the mouse?

[lucasfernog]

We do have it on tao and we could expose it here, but it wouldn't solve your problem since it doesn't give any information about the monitor of the mouse position.

[OceanBelongsToMe]

Can you expose that? Maybe I can calculate the relevant information from the mouse position and monitor coordinates :)
