Zopfli is the most efficient DEFLATE compression algorithm, trading run-time
performance for file sizes that are typically 3-8% smaller than those produced
by zlib with the maximum compression setting. Its output is Deflate-compatible,
so no specialized decoder is needed.
This change was created by running zopflipng against all the PNG files in this
repository. The exact invocation was:
git ls-files --exclude-per-directory=.gitignore -- '*.png' \|
parallel zopflipng -m -y {} {} \;
Files which zopflipng was not able to compress more efficiently were left unmodified.

SVG and PNG versions have been modified to be of the same dimensions.
The sprite now is a 14x14px cog with an additional transparent pixel
above and below. resulting in two 14x16px areas. The added margin solves
the problem of image being cropped when zooming.
