How to style GroupBox without loosing MaterialDesignInXamlToolkit features, to have rounded corners?

@sensboston Currently there is not a great way of extending the default GroupBox style to use rounded corners apart from making a complete local copy of the style (which is of course doable).

You could consider using the MaterialDesignCardGroupBox style to get rounded corners, but you still cannot control the CornerRadius without making a complete local copy of the style.

<GroupBox Header="Card Look" Style="{StaticResource MaterialDesignCardGroupBox}">
  <TextBlock Text="My Content" />
</GroupBox>

Thank you! It's enough for now; maybe devs will add that property in future.
