explicitly close figures in clean_up_and_exit instead of using an atexit function
* graphics.cc (Fdrawnow): Don't register __go_close_all__ as an atexit
function.
* __go_close_all__.m: Delete.
* plot/module.mk (plot_FCN_FILES): Remove __go_close_all__.m from the
list.
* graphics.cc (gh_manager::create_instance): Do register cleanup
function.
* graphics.cc (delete_graphics_objects, delete_graphics_object,
close_figure, force_close_figure): New functions.
(F__go_delete__): Call delete_graphics_objects to do the work.
* graphics.h, graphics.cc (gh_manager::close_all_figures,
gh_manager::do_close_all_figures): New functions.
* graphics.h.in, graphics.cc (close_all_figures): New function.
* toplev.cc (clean_up_and_exit): Call close_all_figures.
* graphics.h.in (uitoggletool::~uitoggletool, uipushtool::~uipushtool,
uitoolbar::~uitoolbar, uipanel::~uipanel, uicontrol::~uicontrol,
uicontextmenu::~uicontextmenu, uimenu::~uimenu, hggroup::~hggroup,
surface::~surface, image::~image, text::~text, line::~line,
axes::~axes, figure::~figure, root_figure::~root_figure):
Don't delete children.
* toplev.cc (SAFE_CALL, IGNORE_INTERRUPT): Rename to OCTAVE_SAFE_CALL
and OCTAVE_IGNORE_INTERRUPT and move to toplev.h. Temporarily set
Vdebug_on_error and Vdebug_on_warning. Reset error_state to zero.
Change all callers.
* graphics.h.in (base_graphics_toolkit::close): New virtual function.
(graphics_toolkit::close, graphics_toolkit::close_all_toolkits):
New functions.
* graphics.cc (gnuplot_toolkit::close): New function.
):
* __init_fltk__.cc (F__init_fltk__): Don't register __remove_fltk__ as
an atexit function.
(F__remove_fltk__): Move to fltk_toolkit::close.
