 4         <Setter.Value>
 5             <ControlTemplate TargetType="VectorModel:Node"> 
 6                      <Canvas>
 7                     <Grid x:Name="RootElement" MinWidth="5" >
 8                         <Grid.RenderTransform>
 9                             <ScaleTransform x:Name="_ScaleTransform" ScaleX="1" ScaleY="1"/>
10                         </Grid.RenderTransform>
