# 
# =item App::Chart::Gtk2::GUI::string_width ($widget_or_layout, $str)
# 
# Return the width in pixels of C<$str> in the font of the given widget or
# layout (either a C<Gtk2::Widget> or a C<Gtk2::Pango::Layout> object).
# 
# =cut
# 
# =item C<< App::Chart::Gtk2::GUI::draw_text_centred ($widget, $region_or_event, $string) >>
# 
# Draw C<string> centred in the window of C<widget>.  If C<widget> isn't
# realized yet then do nothing.  Pango C<word-char> wrapping is enabled, so
# the string is not truncated if it's wider than the window.
# 
# Both windowed and no-window widgets can be given here.  C<$region_or_event>
# gives a region to clip to, or undef to draw everything.
# 
# =cut
# 
# =item App::Chart::Gtk2::GUI::chart_style_class ($class)
# 
# =item App::Chart::Gtk2::GUI::chart_style_widget ($widgetname)
# 
# Setup package C<$class> or widget C<$widgetname> (per
# C<< $widget->set_name >>) to get the Chart graph style settings, which means
# black background and white foreground and text.
# 
# C<$class> can include colons like C<"App::Chart::Gtk2::HAxis"> and they're turned
# into underscores like C<"App__Chart__Gtk2__HAxis"> which is the Gtk class
# name.
