[truetype] Round phantom points after instructions.apodtele-master-patch-56869
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.
