Sets the widget’s clip. This must not be used directly,
but from within a widget’s size_allocate method.
It must be called after gtk_widget_set_allocation() (or after chaining up
to the parent class), because that function resets the clip.
The clip set should be the area that @widget draws on. If @widget is a
#GtkContainer, the area must contain all children's clips.
If this function is not called by @widget during a ::size-allocate handler,
the clip will be set to @widget's allocation.
