Bug Description

qtmir relies on mir::scene::SurfaceObserver::cursor_image_set_to being called whenever the surface cursor name changes.

qtubuntu still uses the deprecated API "mir_cursor_configuration_from_name() && mir_window_configure_cursor". With that, mir::scene::SurfaceObserver::cursor_image_set_to does get called in qtmir.

But once qtubuntu uses the new Mir API for that[1], "mir_window_spec_set_cursor_name() && mir_window_apply_spec()", the SurfaceObserver in qtmir no longer gets notified

Testing with mir_demo_client_cursor:

This works:

    $ mir_demo_server --test-client mir_demo_client_cursor

This doesn't work:

    $ miral-shell --startup mir_demo_client_cursor

OK, the reason this works in the Mir examples is that the implementation is *in the examples*.

Unsurprisingly, libmiral doesn't contain this code.

      . mirplatformgraphics ABI bumped to 12
      . mirclientplatform ABI unchanged at 5
      . mirinputplatform ABI unchanged at 6
      . mircore ABI unchanged at 1
    - Enhancements:
      . Support for MirBuffer API that allows for better management of
        hardware/software buffers.
      . Support for MirPresentationChain API that allows better control
        over {de}queueing of individual buffers {from}to the server.
      . Interim support for MirRenderSurface API that provides a unit of
        renderable for lower level content such as MirBufferStreams and
        MirPresentationChains, etc.. MirRenderSurface API is marked
        deprecated as it (and the relevant entry points) will be renamed to
        MirSurface before general availability. It will initially be used for
        revamping support for EGL drivers.
      . Synchronous version of mir_prompt_session_new_fds_for_prompt_providers()
        API (mir_prompt_session_new_fds_for_prompt_providers_sync()) added for
        convenience.
      . Better name for MirPersistentId-->MirWindowId. MirPersistentId has now
        been deprecated.
    - Bugs fixed:
      . [regression] Unity8 stutters constantly (like half frame rate).
        (LP: #1661128)
      . mir 0.26 - spinner loading animation, minimize, maximize too fast.
        (LP: #1661072)

        fullscreen client starts [in mir_presentation_chain_set_dropping_mode
        ... std::exception::what: Operation not permitted] (LP: #1661508)
      . mir_window_request_persistent_id_sync seg faults when called twice.
        (LP: #1661704)
      . [regression] Windowed clients of nested servers are all black.
        (LP: #1661521)
      . Mir graphics platform ABI broke in series 0.26 but sonames never
        changed (LP: #1662455)
      . Fixes for 0.26 changelog.

      . mir_window_spec_set_cursor_name() doesn't trigger
        mir::scene::SurfaceObserver::cursor_image_set_to. (LP: #1663197)
