title: How to set header style in TabItem?
body: <p>I've created in my Window.Resource a Style that hold the background of the selected TabItem. What I want achieve is set a custom height for the TabItem header, this is my Style:</p>
  
  <pre><code>&lt;Window.Resources&gt;
      &lt;ResourceDictionary&gt;
          &lt;Style x:Key="CustomTabItem" TargetType="{x:Type TabItem}" BasedOn="{StaticResource MetroTabItem}"&gt;
              &lt;Setter Property="Width" Value="Auto"/&gt;
              &lt;Setter Property="Background" Value="Transparent" /&gt;
              &lt;Setter Property="Height" Value="Auto"/&gt;
              &lt;Setter Property="Template"&gt;
                  &lt;Setter.Value&gt;
                      &lt;ControlTemplate TargetType="TabItem"&gt;
                          &lt;Border Name="Border" Background="Transparent"&gt;
  
                              &lt;ContentPresenter x:Name="ContentSite"
                                          VerticalAlignment="Center"
                                          HorizontalAlignment="Left"
                                          ContentSource="Header"
                                          Margin="10,3"&gt;
                              &lt;/ContentPresenter&gt;
                          &lt;/Border&gt;
  
                          &lt;ControlTemplate.Triggers&gt;
                              &lt;Trigger Property="IsMouseOver" Value="True" SourceName="Border"&gt;
                                  &lt;Setter TargetName="Border" Property="Background" Value="Gainsboro" /&gt;
                              &lt;/Trigger&gt;
                              &lt;Trigger Property="IsSelected" Value="True"&gt;
                                  &lt;Setter TargetName="Border" Property="Background" Value="#FFC5C5C5" /&gt;
                              &lt;/Trigger&gt;
                          &lt;/ControlTemplate.Triggers&gt;
                      &lt;/ControlTemplate&gt;
                  &lt;/Setter.Value&gt;
              &lt;/Setter&gt;
          &lt;/Style&gt;
      &lt;/ResourceDictionary&gt;
  &lt;/Window.Resources&gt;
  </code></pre>
  
  <p>usually I add the style to my TabControl like so:</p>
  
  <pre><code>&lt;TabItem Tag="Tab1" Style="{StaticResource CustomTabItem}"&gt;
  </code></pre>
  
  <p>I just want set the header height for all the TabControls that have the <code>CustomTabItem</code> style, any suggestion? </p>
