Rewrite Fl_Window_Driver::resize_after_scale_change() removing calls to Fl_Window::hide() and Fl_Window::show().

Windows are now rescaled with a call to Fl_Window::resize() which has been slightly modified.
Static member variable bool Fl_Window_Driver::in_resize_after_scale_change is created,
and is true if and only if Fl_Window::resize() is called by Fl_Window_Driver::resize_after_scale_change().
This new flag allows Fl_Window::resize() to perform correctly the rescaling of the window.
Fl_Gl_Window::resize() and Fl_Double_Window::resize() also consult the value of
the Fl_Window_Driver::in_resize_after_scale_change flag.
The platform-specific Fl_WinAPI_Window_Driver::resize() and Fl_X11_Window_Driver::resize()
also use  the Fl_Window_Driver::in_resize_after_scale_change flag.
