same Cairo font backend as the default X11 build is also used by the
PGTK build.

The other alternative we considered was to prevent Emacs from starting
under X11 when compiled with PGTK.

The alternative is to have an Emacs that crashes under X11 in various
common situations.  Please read the message in the dialog box.
