This adds a new method to the display server interface to allow the application to notify the ds when there is a guest cursor position update along with the translated local guest cursor position. This makes it possible for the display server to keep the local cursor position in sync with the guest cursor so that window leave events can be detected when the cursor would move into an overlapping window. Wayland currently just has a stub for this, and the X11 implementation still needs some minor tweaking.
