[I'm sure your question is rhetorical, but if it weren't, at one time I
would have said the what could be done is to leave the world of
paternalistic proprietary software and use Free software instead! Sadly,
the paternalistic-proprietary-software thinking has infected Free
software and we increasingly see libraries and tools that do what they
think the user should want them to do, rather than flexibly doing what the
user asks them to do.]

But that does raise the possibly naive question:

Rather that trying to cover up the warning, can we not just do what the
library wants; is it impossible for us to call "gtk_widget_show_all() on
the contents and gtk_window_set_geometry_hints() on the window" before
calling gtk_window_parse_geometry()?
