Detailed Description

Implementations of the favicon *resolvers* that are available in the favicon
proxy by default.  A *resolver* is a function that obtains the favicon from an
external source.  The *resolver* function receives two arguments (``domain,
timeout``) and returns a tuple ``(data, mime)``.
