#800 – Transforms Do Not Affect ActualWidth and ActualHeight

Transforms do not change the values of the original element’s dimensions, as reported by the ActualWidth and ActualHeight properties.  This is true for both LayoutTransforms and RenderTransforms.

    <StackPanel>
        <Button Name="btn1" Content="Apollo" HorizontalAlignment="Center"
                Margin="5"/>

        <Button Name="btn2" Content="Apollo" HorizontalAlignment="Center"
                Margin="5">
            <Button.RenderTransform>
                <ScaleTransform ScaleX="1.5" ScaleY="2.0"/>
            </Button.RenderTransform>
        </Button>

        <Button Name="btn3" Content="Apollo" HorizontalAlignment="Center"
                Margin="5">
            <Button.LayoutTransform>
                <ScaleTransform ScaleX="1.5" ScaleY="2.0"/>
            </Button.LayoutTransform>
        </Button>

        <Button Content="Debug" Click="Button_Click" HorizontalAlignment="Center"
                Margin="10"/>
    </StackPanel>

Notice that when we inspect the elements in the debugger, they all have identical values for ActualWidth and ActualHeight.
