ScrollToRow behavior change

The ScrollToRow method triggers the RowFocusChanging and RowFocusChanged events. In PowerBuilder 7, both events occurred after focus changed to the new row. This behavior was changed in PowerBuilder 9 so that RowFocusChanging could be coded to cancel the scroll. However, this change caused both events to be triggered before focus changed to the new row. In PowerBuilder 9.0.1 Build 7136 and later, the RowFocusChanging event is triggered before the scroll occurs, and the RowFocusChanged event is triggered after the scroll occurs. [CR 345104]
