Re: [csswg-drafts] [css-fonts-4] [varfont] Supported variation font axes and font features are not discoverable

> The canvas text metrics API and the forthcoming Houdini text metrics
 API expose some other font-driven information. However, these APIs 
give you information about a line (or lines) of text, and would 
include things like fallback fonts. 

Yes. At the early Houdini meetings the assumption was that Houdini 
would produce a font metrics API, to query features of a particular 
font (and with the advent of variation fonts, a particular instance). 
However, over time that was seen as less important for 
pollyfiller-writers  than metrics on fonts used together in a text 
segment, which eventually became the text metrics API.

There is still a need to query an individual font instance.
