Re: Chromatic fonts - implementation roundup [via SVG glyphs for OpenType Community Group]

I’d also heard of a Firefox bug in which unitsPerEm is assumed to be 1000.

Could Jonathan, Cameron, or someone else at Mozilla please confirm that this is still a known limitation of Firefox’s OT-SVG impl?

Knowing that would help untangle the issues surfaced by Chris’ post. (Plus, it would be good information for font developers.)

Thanks,
Sairus
