Fixed X11/XDBE double buffering (STR #2152, #2197). Both bugs could only be
seen if configure was run with --enable-xdbe (default in FLTK 1.3, optional
in FLTK 1.1).
src/Fl_Double_Window.cxx/Fl_Double_Window::resize():
STR #2152: deallocate back buffer when window is enlarged in any
dimension to force allocation of a new back buffer. This appears
to be necessary for some window managers (e.g. Cygwin).
src/Fl_Overlay_Window.cxx/Fl_Overlay_Window::flush() and
src/Fl_Double_Window.cxx/Fl_Double_Window::flush():
STR #2197: make sure that the entire overlay window will be drawn
after a window redraw, because Fl_Double_Window::flush(1) erases
the overlay as documented.
