ScrollChanged is called in the OnInput event handler for updating, when the scrollbar value has changed, for given dimension. This is part of the Layouter interface.

(d math32.Dims, sb *Slider)

// when the scrollbar value has changed, for given dimension.
// This is part of the Layouter interface.
func (fr *Frame) ScrollChanged(d math32.Dims, sb *Slider) {
	fr.Geom.Scroll.SetDim(d, -sb.Value)
	fr.This.(Layouter).ApplyScenePos() // computes updated positions
	fr.NeedsRender()
}

// ScrollUpdateFromGeom updates the scrollbar for given dimension
// based on the current Geom.Scroll value for that dimension.
