Add Liberation and Symbola fonts
Removed font_bitstream_vera() and font_dejavu() getters. They are replaced by a family of generic font getters: font() to retrieve the font for a given variant and style, and fonts() to retieve all fonts defined in a fontset.
Add font_families() and font_faces() to retrieve font files organised according to R’s nomenclature of fonts. Conversely there is now font_variants() and font_styles() which organise fonts according to fontconfig’s categories. Also, font_symbol() allows to retrieve a symbol font defined by a fontset (currently only the Symbola fontset defines one).
htmlFontDependency() now takes fonts and collections of fonts (as returned by font_families() and friends) as argument.
htmlFontDependency() now uses the style-linking idiom for generating CSS.
Initial release
Add font_bitstream_vera() and font_dejavu(). The latter require installing the fontDejaVu package from Github: devtools::install_github("lionel-/fontDejaVu").
Implement htmlFontDependency() to include font dependency in web pages or applications.
