Class Description

                                                                      
 A number of different layout classes (TGLayoutManager,               
 TGVerticalLayout, TGHorizontalLayout, TGLayoutHints, etc.).          
                                                                      
                                                                      
 Concerning the TGMatrixLayout class:                                 
                                                                      
 It arranges frames in a matrix-like way.                             
 This manager provides :                                              
 - a column number (0 means unlimited)                                
 - a row number (0 means unlimited)                                   
 - horizontal & vertical separators                                   
                                                                      
 Notes : If both column and row are fixed values, any remaining       
         frames outside the count won't be managed.                   
         Unlimited rows means the frame can expand downward           
         (the default behaviour in most UI).                          
         Both unlimited rows and columns is undefined (read: will     
         crash the algorithm ;-).                                     
         With fixed dimensions, frames are always arranged in rows.   
         That is: 1st frame is at position (0,0), next one is at      
         row(0), column(1) and so on...                               
         When specifying one dimension as unlimited (i.e. row=0 or    
         column=0) the frames are arranged according to the direction 
         of the fixed dimension. This layout manager does not make    
         use of TGLayoutHints.
