Wayland support, and will at least be supported for the foreseeable
future (just without major changes.)

The successor will hopefully be a different toolkit, made by developers
who have sane approaches to handling window-system errors.  But it will
take several years for the other toolkits to catch up with GTK in terms
of Wayland support.
