ScatterChart doesn't support rangeAnnotation. #1665

I would like to use a scatter plot, but I need the range annotations to color part of the background of the chart. This is easy to do using LineChart, but not for ScatterChart even though the rangeAnnotations property is in a common ancestor.

The ability to set this property needs to be exposed in the ScatterChartData through the constructor just as it is exposed in the LineChartData constructor.
