Review comment:
       > Other approach would be to introduce a SPI, that would supply metadata 
(in general) for an image/icon
   
   That sounds a bit backwards. "Metadata" here just means "logical icon ID", 
right? And surely it's the site that actually loads the icon that should 
provide the logical icon ID to look up by?
   
   By the way, do we have an actual use case for this patch yet, i.e. actual 
icons that will be substituted in a future patch? Which icons are those, and 
how many of them are there?
   
   > note that this 'replacement' solves also icons queried by Swing codebase 
that might flow through the system: even if Swing calls getIcon(), it gets a 
wrapper
   
   For Swing-loaded icons, can't clients just update the relevant icons 
directly in UIDefaults, like LAFs do?
