commit 4ddd28a5d9f65e7c5f05bfee9d86a56fa5a67645

Date:   Mon Oct 26 11:48:22 2020 -0700

    Extract font-stretch when converting pango font names to CSS.
    
    Also wrap font-family value in quotes and lower-case the fallback
    generic sans-serif font-family for CSS conformance (though browsers
    don't seem to care).

    [macOS] Replace bogus font name from pango.
    
    Pango on macOS reports ".AppleSystemUIFont" as the name for the
    system-ui alias. This bogus name doesn't work so replace it with
    the fallback Arial.
