Protocol to indicate where text cursor is
https://wayland.app/protocols/text-input-unstable-v3
Marks an area around the cursor as a x, y, width, height rectangle in surface local coordinates.
Allows the compositor to put a window with word suggestions near the cursor, without obstructing the text being input.
If the client is unaware of the position of edited text, it should not issue this request, to signify lack of support to the compositor.
