[Bug 1556457] [NEW] [Resolved Upstream] Demilight (OS/2 weight=350) confuses fontconfig

[Mingye Wang]

Public bug reported:

See https://bugs.freedesktop.org/show_bug.cgi?id=81453 and bug 1468027.

Fontconfig lacks support for many OpenType/TrueType OS/2 font weight
values. This causes a bunch of problems, like mixing up Demilight
(weight=350) and Regular (weight=400).

Although it's possible to write (dirty?) hacks for deb-packed fonts,
this still causes problems for otherwise sourced fonts.
