Максимизация (развёртывание) окна WPF

Question

[Panicrust]

Пишу программу с дизайном в стиле Windows 8 (Flat/Metro).
У главного окна MainWindow.xaml заданы свойства -

WindowStyle="None"
AllowsTransparency="True"

Максимизированное (развёрнутое) окно занимает полностью весь экран, то есть "Панели задач" windows тоже не видно. Можно ли сделать какой-то отступ снизу, либо как-то "отодвинуть" на один слой назад (как в фотошопе, например). Заранее благодарю

Можно использовать Microsoft.Windows.Shell.WindowChrome.
FakeBorder нужен для того, чтобы при развертывании окна клиентская часть не выходила за пределы экрана. Источник не помню, где-то на форумах msdn нашел.

<ControlTemplate x:Key="DefaultWindowTemplate" TargetType="{x:Type Window}">
        <Border Name="FakeBorder" BorderBrush="Green">
            <Border.Style>
                <Style TargetType="{x:Type Border}">
                    <Setter Property="BorderThickness" Value="0"/>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=WindowState}" Value="Maximized">
                            <Setter Property="BorderThickness" Value="{Binding Source={x:Static shell:SystemParameters2.Current}, Path=WindowResizeBorderThickness}"/>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </Border.Style>
            <Border Name="WindowBorder"
