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.
