d8618774be Fix some comment typos. 
These comments weren't updated when we went from 24.8 to 26.6.

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.

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.

11bef13aa5 freetype/truetype: track phantom points across compound glyphs.

ugly code, but let's get all the tests passing first, so that we can
refactor with confidence.
