ScrollView snapToStart #3065
Description
Split out from #2113
Use in conjunction with snapToOffsets. By default, the beginning of the list counts as a snap offset. Set snapToStart to false to disable this behavior and allow the list to scroll freely between its start and the first snapToOffsets offset. The default value is true.
Not directly supported by ScrollViewer. Can be implemented in conjunction with adding snap points (Win 8) to the child of the ScrollViewer.
