            Note, the setAnimateForm means set the animation from TextGroup to Object's Shape
            And on the UI in means "Animate attached shape" in "Effect Option" dialog
            The setTextGrouping means set animation to Object's Text,
            the nTextGrouping is Text Animation Type
            nTextGrouping = -1 is "As one Object", means no text animation.

            The previous call order first do the setTextGrouping and then do the setAnimateForm,
            that will cause such defect: in the setTextGrouping, the effect has been removed,
            but in setAnimateForm still need this effect, then a NULL pointer of that effect will
            be gotten, and cause crash.

            []bHasAnimateForm means the UI has changed, bAnimateForm is it value

            So if create a new textgroup animation, the following animation will never be run!
            Since the \A1\B0Animate attached shape\A1\B1 is default checked.
            And the bHasAnimateForm default is false, and if user uncheck it the value bAnimateForm will be false,
            it same as the TextGroup\A1\AFs default value, also could not be run setAnimateForm.
            if( bHasAnimateForm )
            {
            if( pTextGroup->getAnimateForm() != bAnimateForm )
            {
            pEffectSequence->setAnimateForm( pTextGroup, bAnimateForm );
            bChanged = true;
            }
            }

            In setTextGrouping, there are three case:
            1.  Create new text effects for empty TextGroup
            2.  Remove all text effects of TextGroup (nTextGrouping == -1)
            3.  Change all the text effects\A1\AF start type

            So here is the right logic:
            If set the animation from text to shape and remove text animation,

            Other case,do setTextGrouping first, then do setAnimateForm.
