Styling GridSplitter wpf С#

Я хочу создать свой GridSplitter, как добавление точек на нем (как показано на http://msdn.microsoft.com/en-us/library/aa970265.aspx).

Я также хочу изменить цвет gridsplitter на mouseOver или применить тему Aero.

<Style x:Key="GridSplitterStyle1" TargetType="{x:Type GridSplitter}">
  <Setter Property="Background"
          Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/>
  <Setter Property="PreviewStyle">
    <Setter.Value>
      <Style>
        <Setter Property="Control.Template">
          <Setter.Value>
            <ControlTemplate>
              <Rectangle Fill="#80000000"/>
            </ControlTemplate>
          </Setter.Value>
        </Setter>
      </Style>
    </Setter.Value>
  </Setter>
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type GridSplitter}">
        <Border Background="{TemplateBinding Background}"
                BorderBrush="{TemplateBinding BorderBrush}"
                BorderThickness="{TemplateBinding BorderThickness}"/>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>
