There is now a single shaping implementation, Shaper, for all fonts, replacing Family that only covered a single typeface. A typeface is identified by a name, where the empty string denotes the default typeface. Font is introduced to specify a particular font from the typeface, style, weight and size. Face is changed to an interface for a particular layout and shaping method. The text/shape package is renamed to text/opentype and contains a Face implementation based on golang.org/x/image/font/sfnt. Signed-off-by: Elias Naur <mail@eliasnaur.com>
