I didn't miss it but I didn't want to add all DirectFB command-line
options by hand since there are a _lot_ of them. In case you're
interested, I'm posting the patch we use at the moment.  It adds the
new type GDK_ARG_WINDOWING_OPTION which is detected by matching the
start of the argument string against a backend supplied prefix. This
works well for DirectFB since all our command-line arguments are
prefixed with 'dfb:' but I don't consider this hack overly nice and
would prefer if _gdk_windowing_init_check() would be able to
manipulate its arguments just like gtk_init() and gdk_init().

Salut, Sven
