Re: The current state of rendering and overlap

[Alexei Podtelezhnikov]



It's easy enough to add FT_OUTLINE_OVERLAP to any glyph loaded from a

CFF2 font. Whether that makes sense is one thing I'd like advice about.

There's currently no such code.

I would suggest that CFF2 invent a special charstring to mark overlaps
with FT_OUTLINE_OVERLAP only when necessary. Let us know to implement
it in FreeType.

WOFF2 is moving towards accepting explicit overlap flags. Perhaps CFF2 can spare  a reserved operator or a two-byte operator.
