//helper baseclass to ease retro fitting dialogs/tabpages that load a resource
//to load a .ui file instead
//
//vcl requires the Window Children of a Parent Window to be destroyed before
//the Parent Window.  VclBuilderContainer owns the VclBuilder which owns the
//Children Window. So the VclBuilderContainer dtor must be called before
//the Parent Window dtor.
//
//i.e.  class Dialog : public SystemWindow, public VclBuilderContainer
//not   class Dialog : public VclBuilderContainer, public SystemWindow
//
//With the new 'dispose' framework, it is necessary to force the builder
//dispose before the Window dispose; so a Dialog::dispose() method would
//finish: disposeBuilder(); SystemWindow::dispose() to capture this ordering.
