title: Set IsMouseOver property for the entire control and not on the DrawingData
body: <p>I am drawing a triangle using a Path, and the <code>IsMouseOver</code> property is true only if the mouse pointer is over the triangle. I would like it to be True also when the pointer is over the background of path (transparent). How can I obtain this result? </p>
  
  <pre><code>&lt;!-- language: lang-xml --&gt;
  &lt;Style TargetType="{x:Type Path}"&gt;
      &lt;Setter Property="Stretch" Value="Uniform"/&gt;
      &lt;Setter Property="Fill" Value="#FF9C9C9C"/&gt;
      &lt;Setter Property="Cursor" Value="Hand"/&gt;
      &lt;Style.Triggers&gt;
          &lt;Trigger Property="IsMouseOver" Value="True"&gt;
              &lt;Setter Property="Fill" Value="#FFBDBDBD"/&gt;
              &lt;Setter Property="Effect"&gt;
                  &lt;Setter.Value&gt;
                      &lt;DropShadowEffect x:Name="DropShadowEffect" BlurRadius="12" Color="#FF9C9C9C" ShadowDepth="0"/&gt;
                  &lt;/Setter.Value&gt;
              &lt;/Setter&gt;
