6deea24143 Add a truetype.Face type.
Its implementation is mostly a copy/paste of the freetype.Context type.
Follow-up commits will make it more efficient.

Also add an example that uses a truetype.Face and the
golang.org/x/exp/shiny/font package to draw text.

7e2154db58 Delete the f26dot6 type in favor of fixed.Int26_6. 2015-08-18 16:47:46 +10:00
Nigel Tao
43fc220ebd Make f26dot6 methods prefix, not infix.
This is in anticipation of removing the f26dot6 type entirely. Instead,
we will use the fixed.Int26_6 type from golang.org/x/image/math/fixed.
