/* When changing the text of the cursor_label, it requests a resize
* bubbling up to containers, up to the display shell. If the resizing
* actually happens (even when the size is the same), a full "draw"
* signal is triggered on the whole canvas, which is not a good thing
* as a general rule (and very bad on some platforms such as macOS).
* It's too late to do anything when processing the "draw" signal
* because then we can't know if some part of the invalidated
* rectangle really needs to be redrawn. What we do is not propagate
* the size request back to container parents. Instead we queue the
* resize directly on the widget.
*
* Note that the "resize-mode" property seems to be unrecommended now
* (though only the public functions are deprecated, we get no
* deprecation setting as a property) but it's still here in GTK3 and
* still seems like the proper way to avoid propagating useless
* no-actual-size-change resizes to container widgets.
* XXX On GTK4, we will likely have to test again and if it's still a
* problem, make a different fix.
*
* See discussion in MR !572.
