typedef CGrafPtr GWorldPtr;
An offscreen graphics world in color QuickDraw contains a CGrafPort structureand its handles to associated PixMap and ColorTable structuresthat describes an offscreen graphics port and contains references to a GDevice structure and other state information. The actual data structure for an offscreen graphics world is kept private to allow for future extensions. However, when your application uses the NewGWorld function to create an offscreen world, NewGWorld returns a pointer of type GWorldPtr by which your application refers to the offscreen graphics world.
On computers lacking color QuickDraw, GWorldPtr points to an extension of the GrafPort structure.
