Browse source

future use.

/*
This code will allow us to access TrueType/OpenType font tables from
fontconfig. If we want to implement features like the so-called "OS/2"
table which contains typographic family info ("give me a list of 'script'
fonts with slab serifs") and stuff like the font's correct typographic
line height and its xHeight, this is where we get that info.
For more information, see http://www.microsoft.com/typography/otspec/
