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

 Create a graphics context, registers GC in GCPool.

 Copy a graphics context.

 Delete graphics context.

 Graphics context assignment operator.

 Not inline due to a bug in g++ 2.96 20000731 (Red Hat Linux 7.0).

 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.

 Set font.

 Set sub window mode (kClipByChildren, kIncludeInferiors).

 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).

 Print graphics contexts info.

 Returns GC mask as a string - used in SavePrimitive().

 Save graphics context info as a C++ statement(s) on output stream out
