Warning
gtk_style_context_cancel_animations has been deprecated since version 3.6 and should not be used in newly-written code. This function does nothing.
Stops all running animations for region_id and all animatable
regions underneath.
A NULL region_id will stop all ongoing animations in context,
when dealing with a GtkStyleContext obtained through
gtk_widget_get_style_context(), this is normally done for you
in all circumstances you would expect all widget to be stopped,
so this should be only used in complex widgets with different
animatable regions.
