  In that blog I see it mentions the kawase blur and downscaling, but this is a different method.
  While that in the blog downscales, blurs the image and then upscales, this method here combines the two so it only downscales and upscales.
  You can read more info and performance comparison about the dual kawase blur (starts at page 21):
