title: Why does a QuadraticBezierSegment render differently between drawing with a line and animating with a DoubleAnimationUsingPath.PathGeometry?
body: <p>I have defined a <code>QuadraticBezierSegment</code> object as the <code>Data</code> property of a <code>Path</code> object:</p>
  
  <pre><code>&lt;Path Stroke="Red" StrokeThickness="5"&gt;
      &lt;Path.Data&gt;
          &lt;PathGeometry&gt;
              &lt;PathFigure StartPoint="450,250" IsClosed="False"&gt;
                  &lt;QuadraticBezierSegment Point1="245,-50" Point2="0,25" /&gt;
              &lt;/PathFigure&gt;
          &lt;/PathGeometry&gt;
      &lt;/Path.Data&gt;
  &lt;/Path&gt;
  </code></pre>
  
  <p>It is shown below in red, and shows the curve that I expected.:</p>

  <p>However, when this same curve is used in a path animation, the path of the animated element is NOTHING like the path of the line shown in the image above. [Please note that this is only part of the animation that I've been creating.]</p>
  
  <pre><code>&lt;Ellipse Width="50" Height="50" Fill="#FF01ADEF" Stroke="Black" StrokeThickness="3"&gt;
      &lt;Ellipse.Triggers&gt;
          &lt;EventTrigger RoutedEvent="Loaded"&gt;
              &lt;BeginStoryboard&gt;
                  &lt;Storyboard RepeatBehavior="Forever"&gt;
                      &lt;Storyboard Storyboard.TargetProperty="(Canvas.Top)" BeginTime="0:0:3"&gt;
                          &lt;DoubleAnimationUsingPath Duration="0:0:1.5" 
                              AccelerationRatio="0.2"&gt;
                              &lt;DoubleAnimationUsingPath.PathGeometry&gt;
                                  &lt;PathGeometry&gt;
                                      &lt;PathFigure StartPoint="450,250" IsClosed="False"&gt;
                                          &lt;QuadraticBezierSegment 
                                              Point1="245,-50" Point2="0,25" /&gt;
                                      &lt;/PathFigure&gt;
                                  &lt;/PathGeometry&gt;
                              &lt;/DoubleAnimationUsingPath.PathGeometry&gt;
                          &lt;/DoubleAnimationUsingPath&gt;
                      &lt;/Storyboard&gt;
                      &lt;Storyboard Storyboard.TargetProperty="(Canvas.Left)" 
                          BeginTime="0:0:3" &gt;
                          &lt;DoubleAnimation Duration="00:00:1.5" From="400" To="0" 
                              DecelerationRatio="0.2" /&gt;
                      &lt;/Storyboard&gt;
                  &lt;/Storyboard&gt;
              &lt;/BeginStoryboard&gt;
          &lt;/EventTrigger&gt;
      &lt;/Ellipse.Triggers&gt;
  &lt;/Ellipse&gt;

  <p>Does anybody know why that is and what I have to do to make the animation path actually follow the path shown in the image?</p>
