that would get complicated, much easier would be to write a poscript backend
to gdk. then one would somehow create a widget that would be drawn on the
poscript instead of X say:

w = gtk_drawingarea_new();
gtk_widget_set_backend(w,GDK_POSTCRIPT);

the w->window would then be realized as a postcript drawable on which all
the gdk_draw stuff would work

another way would be like this. create a poscript drawable, (a copy of
the widget's window), set the widget's ->window to it, generate an expose
event, and set ->window back
