// This class represents "non-owned" window. A window is owned by another
// window if it has a parent and is positioned within the parent. For example,
// wxFrame is non-owned, because even though it can have a parent, it's
// location is independent of it.  This class is for internal use only, it's
// the base class for wxTopLevelWindow and wxPopupWindow.
