A surface can change the pointer image when the surface is the pointer
focus of the input device. Wayland doesn't automatically change the
pointer image when a pointer enters a surface, but expects the
application to set the cursor it wants in response the the motion
event. The rationale is that a client has to manage changing pointer
images for UI elements within the surface in response to motion events
anyway, so we'll make that the only mechanism for setting changing the
pointer image. If the server receives a request to set the pointer
image after the surface loses pointer focus, the request is ignored.
To the client this will look like it successfully set the pointer
image.

The compositor will revert the pointer image back to a default image
when no surface has the pointer focus for that device. Clients can
