Parent windows should be set on dialogs, toolboxes, or other
"auxiliary" surfaces, so that the parent is raised when the dialog
is raised.
Setting a null parent for a child window removes any parent-child
relationship for the child. Setting a null parent for a window which
currently has no parent is a no-op.
