Supplying fonts for WebGL use-case

[yjbanov]

When rendering to WebGL, fallback fonts provided by the browser are not available. The application must provide its own fonts. Let's say the app starts with a set of Uint8Arrays containing TTF, perhaps downloaded using fetch():

• What is the sequence of steps that an app must perform to get to a FormattedTextFragment that's laid out using the provided font set?
• What happens if no glyph is found in the font set?
• How is the font chosen for a particular FormattedTextFragment communicated back to the application such that the application is able to render it?

How is the font chosen for a particular FormattedTextFragment communicated back to the application such that the application is able to render it?

Update: #29 answers this question.
