Restricted Application added a subscriber: Frameworks.

REVISION SUMMARY
  This allows users of IconItem to know the aspect ratio of the
  source document, which can be used to size the item or set
  applet size hints to accomodate non-square images better.
  
  This will be used in a patch to Kicker/Dashboard that ports
  a use of Image in its CompactRepresentation to IconItem to
  get the hover highlight effect even for a custom button image.
