d91c1d6844 Remove Point methods other than Add, Sub, Mul. 
This is in anticipation of removing the Point type entirely. Instead, we will
use the fixed.Point26_6 type from golang.org/x/image/math/fixed.

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

bb775957cb freetype/truetype: propagate the useMyMetrics flag to nested components. 
Also increase the maximum recursion depth from 4 to 8, since some
x-deja-vu-sans-oblique glyphs are actually depth 4. It's an arbitrary
limit. The C Freetype code doesn't seem to limit recursion (below
whatever the font says it needs), but it seems safer to have a limit.
