Barra de desplazamiento de estilo Apple WPF

Question

Estoy tratando de reducir el tamaño del control de la barra de desplazamiento y hacerlo más "Apple", ya que se ajustaría muy bien a mi interfaz.

Lo que estoy tratando de lograr es algo que se parece a esto:

Hasta ahora todo lo que tengo es esta

 <Style TargetType="{x:Type ScrollBar}"> 
      <Setter Property="Stylus.IsFlicksEnabled" Value="True" /> 
      <Setter Property="Background" Value="#8C8C8C" /> 
      <Setter Property="Width" Value="8"/> 
      <Setter Property="MinWidth" Value="8" /> 
     </Style> 

XAML de Trabajo

La implementación puede ser encontrado en Apple Style Scrollbar in WPF

No es muy bonito y honestamente no recuerdo de dónde vino, hay algo similar a lo que buscas en uno de mis proyectos aquí, probablemente haya mucho en el estilo que no se requiere o es incorrecto, pero también puede darle una oportunidad.
