   \brief The Resource class provides access to named resources.
 
   The resources may be provided from files or other sources.
 
   The allSounds() function returns a list of all the sounds available.
   A particular sound can be searched for using findSound().
 
   Images can be loaded with loadImage(), loadPixmap(), loadBitmap()
   and loadIconSet().
