Re: [csswg-drafts] [css-fonts-4] What does "italic values less than or equal to 0" mean in "Matching font styles"?

TrueType doesn't have 'italic' defined as a registered variation axis. Slant is defined (with 'slnt' tag), but this is very different from 'italic', even though in some cases the results (the way glyphs are rendered) can be similar. So, while slant angle can be defined as a negative value, it's not the same as 'italic', where [0..1] is a valid range, and where, in most of the actual implementations the variation axis is used as an on/off switch for regular / italic transition.
