    Description

      If Wayland surfaces have a bufferScale != 1, the wrong positions are being sent to the clients.

      This is because QWaylandQuickItem::mapToSurface assumes that QWaylandSurfaces::size is in surface coordinates, but it's actually in pixel coordinates.

      We have APIs for telling the clients to set a buffer scale, WaylandOuput.scaleFactor, so this is a pretty serious issue.
