     There is a performance issue that the Toolkit.getImage(url) needs 
to check  if @2x, @3x, ... exist for any given image. It especially 
takes a long time  when images are stored on a remote server.

   May be it is better to have a system property which can contain a 
list of possible suffixes and used by Toolkit.getImage(...) methods for 
resolution variants loading.
