Defines how content overflowing a given area should be handled.
This is used in gtk_widget_set_overflow(). The
GtkWidget:overflow property is modeled after the
CSS overflow property, but implements it only partially.
No change is applied. Content is drawn at the specified position.
Content is clipped to the bounds of the area. Content
outside the area is not drawn and cannot be interacted with.
