I think this is a great idea - my interest would probably be atypical  
in that I would
love to have a cross-platform system on which to hang a 2D/3D  
scientific visualization
library.

I'm not so sure about this requirement - from an efficiency standpoint  
in applications
such as image processing it is best to be able to discriminate between  
integral and
continuous screen scaling.

As far as the demo program :

int main(int argc, char* argv[])
{
     window w = create_window();
     w->title("Example window");
     w->contain(create_button(w, "Hello, world!"));
     wait_for_signal(w->delete_signal);
}

why not :

int main(int argc, char* argv[])
{
     window w("Example window");	// more consistent with button syntax  
below
     w.add(button("Hello, world!"));       // no need to have w be a  
pointer?
     w.wait_for(delete_signal());
}

or something like that.
