Overhaul FLTK plotting and printing * gl2ps-renderer.cc: Force execution of GL commands before gl2psEndPage to avoid missing primitives in output. Enable error output of gl2ps, check return value of gl2psBeginPage for error. * __init_fltk__.cc: Avoid redraw of the OpenGL and the plot window if not needed. Let FLTK do the resizing of the canvas, the menubar and the statusbar. This was done by creating a resize_dummy and set this as resizable for the plot_window group. Previously this was done inside draw(). Avoid timing issues with fltk_maxtime (removed) and other hacks with multiple Fl::check and redraw () calls. You can use flush and glFlush if you really need to force a immediate redraw. Remove print_mode in draw () and print directly without waiting that FLTK flushes its buffers. This fixes bug #42458 and #40215 Manually placement of the toolbar is only done once when hiding or showing the menubar. (update_toolbar_position) set(gcf, "position", [x, y, w, h]) is now handled by figure::properties::ID_POSITION which calls update_position * __add_default_menu__.m: Remove now unneeded hacks for the menubar.
