STR#3093 continued: deleted the Fl_Shaped_Window class. Instead, added new member function Fl_Window::shape(Fl_Image*)
that gives a non-rectangular shape to a standard window. The benefit is that it works with Fl_Double_Window and Fl_Menu_Window as well.
It also works for free with Fl_Gl_Window on the X11 platform only.
