Adding a bindable Off state Color for Switch

[Andy-Donegan]

Description

Currently you can set the OnColor state for a switch but can not set the OffColor state. This leads to having to use a custom solution for myself. This Stack Question highlights the issue when placing a Switch on a Black/dark background the off state dissapears into the background and you are just left with the Thumb selector.

 <Style x:Key ="ToggleSwitch" TargetType="Switch">

            <VisualStateGroupList>
                <VisualStateGroup x:Name="CommonStates">
                    <VisualState x:Name="On">
                        <VisualState.Setters>
                            <Setter Property="OnColor"
                            Value="Green" />
                        </VisualState.Setters>
                    </VisualState>
                    <VisualState x:Name="Off">
<!-- Here is the new suggested proper of OffColor -->
                        <VisualState.Setters>
                            <Setter Property="OffColor"
                            Value="Gray" />
                        </VisualState.Setters>
                    </VisualState>
                </VisualStateGroup>
            </VisualStateGroupList>
        </Setter>
    </Style>

Intended Use-Case

My current app requires a Dark background (black currently) using the Switch with the ability to set the offstate color would allow me to use the Switch in any coloured environment.
