Differences with the official image

The differences with plantuml/plantuml-server are:

• Based on Alpine Linux, not Debian.
• Runs on the Zulu OpenJDK.
• PLANTUML_LIMIT_SIZE raised to 16384 so you can generate bigger diagrams.
• Installs a plantuml.skin with a few overrides. (in beta, doesn't work well)
• Installs a rakuten.pu library with a few definitions to get you started. Just include it with !include rakuten.pu at the start of your diagram.
• Comes with a few fonts:
  • Mulish is installed and poses as the Rakuten Sans font, which it is visually similar to (and a decent fallback for when generating PNG diagrams). Generated SVG images correctly inject the font-family: 'Rakuten Sans' style, too.
  • Noto Sans and Noto Sans JP, recommended by the ReX typography guidelines. Noto Sans is set as the default sans-serif font.
  • Fira Code, set as the default monospace font.
  • Font Awesome 5 Free.
