    ◆ VC_DONTCOPYDATA

    #define VC_DONTCOPYDATA

    Speed-up flag. PointObject::ResizeObject() usually copies all old data into a new bigger memory block. This flag suppresses the copying to save memory bandwidth.

    Warning
    If this flag is set a function must handle all tags on their own. Only set it if you know what you are doing.

    ◆ VC_DONTCLEARDATA

    #define VC_DONTCLEARDATA

    This flag prevents PointObject::ResizeObject() to clear the memory during its data initialization.
