    windowPreviews: Replace border with scale effect
    
    We currently use a thick border to indicate the hovered/focused preview. It
    works well for that purpose, but is a bit in the face. Slightly scaling up
    the preview still provides a clear indication, but in a more subtle and
    elegant way.
