WPF中如何将ScrollViewer的滚动条放到左侧

[为轮子而生]

如题，有一个需求必须要这样做，所以请各位大师勿问为何，只说解决方法即可，谢谢

如果真要用其他方法代替，也请不要影响鼠标滚轮和其他滚动界面应有的特性

编辑ScrollViewer的control template。 用blend的话就比较简单， 右键scrollViewer编辑模板， 进去后把vertical scrollbar在grid的位置放到左边，

<Style TargetType="{x:Type ScrollViewer}">
                            <Setter Property="Template">
                                <Setter.Value>
