Class Description

                                                                      
 TGGC and TGGCPool                                                    
                                                                      
 Encapsulate a graphics context used in the low level graphics.       
 TGGCPool provides a pool of graphics contexts.                       
                                                                      

 Create graphics context pool.

 Delete graphics context pool.

 Delete graphics context if it not used anymore.

 Get the best matching graphics context depending on values.

 Try to find matching graphics context. On success returns the amount
 of matching bits (which may be zero if masks have no common bits),
 -1 on failure (when there are common bits but not a single match).

 Update graphics context with the values spcified in values->fMask.
