Class Description

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

 Create a graphics context.

 Copy a graphics context.

 Delete graphics context.

 Update values + mask.

 Set attributes as specified in the values structure.

 Set graphics context drawing function.

 Set plane mask.

 Set tile pixmap for tiling operations.

 Set 1 plane pixmap for stippling.

 X offset for tile or stipple operations.

 Y offset for tile or stipple operations.

 True if graphics exposure should be generated.

 X origin for clipping.

 Y origin for clipping.

 Bitmap for clipping.

 Patterned/dashed line offset.

 Set dash pattern. First use SetDashOffset() if not 0.

 Set arc mode (kArcChord, kArcPieSlice).
