Historically, fltk-1 has always used window-relative rather than parent-relative origins. This often causes confusion, but is easily addressed (simply query the x(), y() offsets in your draw method then add those on to your positions...) For fltk-2 the co-ordinate frame was made parent-relative, as that seemed the more "normal" choice. At some point, fltk-3 will offer a choice...
