@name           PNG Checker for Brave Image Search
@namespace      github.com/openstyles/stylus
@version        1.0.0
@description    Hate when scummy image sites with fake png checkerboard shows up in an image search? This can help you check if a PNG is actually transparent by placing an animated grid behind it.
