## Detailed Description

SplineControlAnimation is an animation type derived from QVariantAnimation which defines how spline control points are animated. It can make use of QVariantAnimation functionality and properties for its animations, such as `duration` and `easing`. These animations are housed inside a QParallelAnimationGroup and hence will run in parallel. This animation will not affect the main points of the SplineSeries, but only the two control handles on either side of the point. Each of the control points are linearly interpolated in succession.

This example shows how to use both a SplineControlPointAnimation and a GraphPointAnimation to define animations for both the main series of points and the control points of a SplineSeries:

     import QtGraphs

     GraphsView {
         SplineSeries {
             GraphTransition {
                 GraphPointAnimation { duration: 1000; easingCurve.type: Easing.OutCubic  }
                 SplineControlAnimation { duration: 1000; easingCurve.type: Easing.OutCubic }
             }
         }
     }
