The site layout icons use the version 1 of this font.
This new version uses a different CSS markup,
so we can use both simultaneously.
It's currently not possible to get rid of the former version,
as the following glyphs are missing from the new:
- tools (header)
- question (header)
- settings (footer)
- globe (footer)
The following icons are available in v3 but will stay v1 to be coherent
with the remaining:
- braille (header)
- flag (footer)
The v3 is intended to provide a richer UI at tool level.
So the offered guideline is v1 for the site layout, v3 for tools.
