  No but it is already being used for icon caching.

  When your screen is scaled 125%, the application gets a dpr of 2.
  When you go back to 100%. the thumbnails in `~/.cache/thumbnails/large` and 
`~/.cache/thumbnails/normal` will be used again.
  Meaning you will have two sets of previews.

~/.cache/thumbnails/normal@2x for 256*256 (i.e 128*128@2x) and 
~/.cache/thumbnails/large@2x for 512*512 (i.e 256*256@2x)
