Added new method Fl_Copy_Surface::draw_decorated_window()

that copies a window to the clipboard together with its title bar and borders.
This requires very little new code because the capture of window decorations
is shared with the Fl_Paged_Device::print window() method.
The device test program is changed to call the new method.
