Subject: 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.
