When I make an effect and the set the text build type it does not get assigned.
Dim ScaleWidthEffect As Aspose.Slides.Animation.IEffect = pres.Slides(0).Timeline.MainSequence.AddEffect(animShape, Aspose.Slides.Animation.EffectType.GrowShrink, Aspose.Slides.Animation.EffectSubtype.None, Aspose.Slides.Animation.EffectTriggerType.WithPrevious)
ScaleWidthEffect.TextAnimation.BuildType = Animation.BuildType.AllParagraphsAtOnce
