/* GTK has a general architectural assumption that gsize is pointer-sized
* (equivalent to uintptr_t), making it non-portable to architectures like
* CHERI where that isn't true. If a future release relaxes that
* assumption, changes will be needed in numerous places.
* See also https://gitlab.gnome.org/GNOME/glib/-/issues/2842 for the
* equivalent in GLib, which would be a prerequisite. */
