wip: Dynamic cursor api

This app has a custom animated cursor that is made from a
paintable. The cursor also uses a 96x96 image for a 32s32
cursor, so it can remain sharp on scaled displays.

-Overview of Changes in 4.15.0, 21-04-2024
-=========================================
-
-This release changes the default GSK renderer to be Vulkan, on
-Wayland. Other platforms still use ngl.
-
-The intent of this change is to get wider testing and verify that
-Vulkan drivers are good enough for us to rely on. If significant
-problems show up, we will revert this change for 4.16.
-
-You can still override the renderer choice using the GSK_RENDERER
-environment variable.
-
----
-
-This release also changes font rendering settings by introducing
-a new high-level gtk-font-rendering settings which gives GTK more
-freedom to decide on font rendering.
-
-You can still use the low-level font-related settings by changing
-the new property to 'manual'.
-
----
-
-* GtkColumnView:
- - Fix infinite loops in dispose
- - Fix problems with weak ref cycles in GtkExpression

-* GtkGraphicsOffload:
- - Add a black-background property
-
-* Settings:
- - Add a new gtk-font-rendering setting
-
-* Accessibility:
- - Add support for GetRangeExtents to GtkAccessibleText
- - Add support for GetOffsetAtPoint to GtkAccessibleText
- - Implement GtkAccessibleRange for scrollbars
-
-* GDK:
- - Add a callback-based cursor API

-* GSK:
--  Use the Vulkan renderer by default
- - Avoid an infinite recursion with offscreens in some cases
- - Optimize graphics offload to make it more likely that compositors
-   can use direct scanout
-
-* X11:
- - Fix some confusing debug messages
- - Drop a no-longer-relevant optimization that was interfering with
-   getting the current window manager capabilities
