Sets a list of backends that GDK should try to use.
This can be be useful if your application does not
work with certain GDK backends.
By default, GDK tries all included backends.
For example,
gdk_set_allowed_backends ("wayland,quartz,*");
nstructs GDK to try the Wayland backend first,
followed by the Quartz backend, and then all
others.
If the GDK_BACKEND environment variable
is set, it determines what backends are tried in what
order, while still respecting the set of allowed backends
that are specified by this function.
The possible backend names are x11, win32, quartz,
broadway, wayland. You can also include a * in the
list to try all remaining backends.
This call must happen prior to Display.open,
gtk_init(), gtk_init_with_args() or gtk_init_check()
in order to take effect.
