[truetype] Round phantom points after instructions.

According to specifications, phantom points might be instructed to
fit them to grid. Then rounding them before instructions might
interfere. Other points are not touched before instructions
either.

* src/truetype/ttgload.c (TT_Hint_Glyph): Delay phantom point
rounding until after instructions are applied.
