Re: The current state of rendering and overlap

[Skef Iterum]

CFF2 is released, has been for years. As far as I know there's no solid 
convention for ignoring unrecognized operators in a CharString, so this 
would be CFF2 minor 1 at best. Which would be years out in terms of 
support.

Practically speaking I don't think this could wind up being a "this 
glyph has overlap" flag, as in CFF2 overlap is valid anywhere. If 
something were added it would be more like a "this glyph doesn't have 
overlap, you can optimize the rendering" flag.

Behdad - there's no provision for a relevant flag in VARC currently, 
correct? (I'm not sure there was one in the glyf-based system, as I 
don't remember a place where the flag would have lived.)
