DisposeGWorld Dispose of a GDevice structure and sub structures
#include <QDOff screen.h> Graphics Devices
void DisposeGWorld( off screenGWorld );
GWorldPtr off screenGWorld ; offscreen GWorld
returns none
If an offscreen graphics device was created, DisposeGWorld disposes of its
GDevice structure and sub structures.
Call DisposeGWorld only when the application no longer needs the off screen
buffer. If the current device was the offscreen device attached to
off screenGWorld, the current device is reset to the device stored in the global
variable MainDevice.
