It is well known that some old fonts like Microsoft core fonts have bad/buggy
hinting (MS hides the problem by adding font-specific workarounds in its text
stack). They should certainly never be used to evaluate if a general default
is good or not.

(that is also something to consider before activating the patented bytecode
engine: in-fonts hints are not necessarily better than what freetype
auto-computes in many cases)

Luxi Mono is not the Red Hat/Fedora monospaced font and is not even in the
distribution.

Unfortunately it is very difficult to get two people to agree on the right
hinting level.
