  "Tux Mono" is a flattened, colourless version of "New Tux" by gg3po
  (https://commons.wikimedia.org/wiki/File:NewTux.svg), which is itself based
  on the original Tux by Larry Ewing (lewing@isc.tamu.edu), made with The GIMP
  (https://commons.wikimedia.org/wiki/File:Tux.png).

Modifications made for this site:
  - Flattened to a single colour (#456387) so the icon matches the Windows and
    macOS platform icons on the download page. The light areas (belly, face,
    feet, eyes) are knocked out through an SVG mask instead of being painted
    white, so the icon sits on any background.
  - Removed the leftover gradient fills, hairline construction strokes and
    Inkscape editor metadata from the original file. No outlines were redrawn.
