Can we define an implicit style for `MetroWindow` for the entire application? E.g. in `Application.Resources`: ``` <Style TargetType="{x:Type mah:MetroWindow}"> <Setter Property="TitleCharacterCasing" Value="Normal" /> </Style> ``` This doesn't seem to work, but adding an x:Key and specifying on a per-view level works just fine. The Clean and VS styles seem to imply it should work?
