windowPreview: Allow to disable overlay

Browse Source 
WindowPreviews now contain and manage overlaid elements like close
button or title label themselves. That's generally better, but right now
the only way to disable those overlays (for example during transitions)
is to prevent any hover or focus events from getting to the preview.

Instead, add some explicit API for enabling or disabling overlay support.
