org.eclipse.swt.graphics.Transform.translate()
Modifies the receiver so that it represents a transformation that is equivalent to its previous transformation translated by (offsetX, offsetY). @param offsetX the distance to translate in the X direction @param offsetY the distance to translate in the Y direction @exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed
