fltk toolkit requires figure units to be "pixels". Bug # 35430. * graphics.cc (root_figure::properties::get_boundingbox): New function. * graphics.h.in (root_figure::properties::get_boundingbox): New function. * __init__fltk__.cc (class plot_window::draw,redraw,handle): Use get/set boundingbox (units are fixed to pixels) rather than get/set position. Add plot_window::get_figure_postion, which returns figure position in pixels.
