Notes

Font Variations

• Decision: add a pango_font_face_is_named_instance / pango_font_face_is_variable
• To investigate: why is font variation updating broken again

Color Emoji

• Need to update pango color emoji data / itemizer
• Need to make the emoji chooser more robust against missing emoji fonts

GTK4 needs / wants

• Nothing in particular, but if gtk4 grows general transformations, the font rendering may need some tweaks

Missing APIs

• Want to get representative pairs for ligatures
• Want to get data for cv tables

Subpixel positioning

• 4x4 phases. Not sure we need an api to set this
• make cairo return subpixel metrics
• pass unrounded positions to cairo, and make cairo round to subpixel positions internally

Font installation

• Nate wants to get docs to be available in yelp
• Zip files are too varied to pick things out there
