Fl_Window_Driver::set_popup_window(), Fl_Screen_Driver::screen_boundaries_known()

Fl_Window_Driver::set_popup_window() is to be used to declare a window should be
positioned relatively to a previously mapped other window.  This allows a platform
to process such windows differently from other windows if needed.
Menu and tooltip windows are so declared.

A call to Fl_Window_Driver::set_popup_window() also allows to distinguish a real
menu or tooltip window from a window marked by Fl_Window::set_menu_window()
or by Fl_Window::set_tooltip_window() but that's not a real menu or tooltip.

New member function bool Fl_Screen_Driver::screen_boundaries_known() returns
true by default. A platform where the position of windows inside a screen is hidden
(e.g., Wayland) returns false. This allows FLTK to refrain from trying to make sure
a computed position is inside a screen.
