Class Description

                                                                      
 TGDimension, TGPosition, TGLongPosition, TGInsets and TGRectangle    
                                                                      
 Several small geometry classes that implement dimensions             
 (width and height), positions (x and y), insets and rectangles.      
 They are trivial and their members are public.
