Add MetaCursorTracker, a new helper for tracking the cursor sprite Under X, we need to use XFixes to watch the cursor changing, while on wayland, we're in charge of setting and painting the cursor. MetaCursorTracker provides the abstraction layer for gnome-shell, which can thus drop ShellXFixesCursor. In the future, it may grow the ability to watch for pointer position too, especially if CursorEvents are added to the next version of XInput2, and thus it would also replace the PointerWatcher we use for gnome-shell's magnifier. https://bugzilla.gnome.org/show_bug.cgi?id=705911

Clean up include macros mess The order and way include macros were structured was chaotic, with no real common thread between files. Try to tidy up the mess with some common scheme, to make things look less messy.

cursor-tracker: Split the code that loads MetaCursorReferences out The plan here is to move the usage of these interfaces to the consumer, and then slam the code into backends.

cursor-tracker: Add X11 cursor tracker backend The intention is to use this to actively track the cursor position given a fixed interval when needed, e.g. when screen casting. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391

cursor-tracker: Add way to force tracking cursor position On X11 we won't always receive cursor positions, as some other client might have grabbed the pointer (e.g. for implementing a popup menu). To make screen casting show a somewhat correct cursor position, we need to actively poll the X server about the current cursor position. We only really want to do this when screen casting or taking a screenshot, so add an API that forces the cursor tracker to track the cursor position. On the native backend this is a no-op as we by default always track the cursor position anyway. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391

core: Centralize cursor renderer and tracker updates These use now more of a "pull" model, where they receive update notifications and the relevant input position is queried, instead of the coordinates being passed along. This allows to treat cursor renderers all the same independently of the device they track. This notifying of position changes should ideally be more backend-y than core-y, a better location will be figured out in future commits.

cursor-tracker/x11: Also update sprite when updating position Without doing this, we'd use the same sprite that was last set by mutter, most likely a leftptr cursor, and fail to update when e.g. moving the pointer above a text entry and the displayed cursor updated to a cursor position marker. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1391

backend: Cleanup cursor tracker on shutdown It keeps references to cursors, and cursors keep references to DRM buffers. In order to be able to clean up on exit, explicitly destroy the cursor tracker on shutdown. We can't rely on GObject reference counting, as gjs might hold onto a reference until it's garbage collected. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1822>
