John Ericson 4c0d7da183 Get rid of all with { inherit... } and just used let inherit...
The old forms presumably predates, or were made in ignorance of,
`let inherit`. This way is better style as the scoping as more lexical,
something which Nix can (or might already!) take advantage of.

FreeType is a portable and efficient library for rendering fonts. It
supports TrueType, Type 1, CFF fonts, and WOFF, PCF, FNT, BDF and PFR
fonts. It has a bytecode interpreter and has an automatic hinter called
autofit which can be used instead of hinting instructions included in
fonts.
