freetype/truetype: make a (sub-)glyph's points an explicit part of a

Hinter's state, instead of having a glyph shrink and restore its
points around hinting.

freetype/truetype: fix rounding for negative numbers to match the C
...
Freetype implementation.
The spec is the "Order of rounding operations" part of
https://developer.apple.com/fonts/TTRefMan/RM02/Chap2.html#rounding
but it wasn't exactly clear to me what "the negative round value
closest to zero" was: if the phase is 1/4, was that value -1/4 or
-3/4? Anyway, the Go code now follows the C code, and code trumps
documentation.

freetype/truetype: add explicit graphics state.

These new opcodes aren't unit-tested per se, but they will be
exercised by an end-to-end hinting test of the Luxi fonts.
