Re: [css-inline] Baseline Alignment Ahem Variant Needed

+John & Rossen & Dominik for the question at the end. (Sorry if I added the wrong person, but I'm hoping you could find the answer out 😊)

In the font I attached to the previous email, I modified the control points of all the glyphs. I subtracted 200 from all the glyphs' Y-coordinates, as well as from the font's ascent and the font's descent. Then I fixed up the paths for the É and p glyphs so their edges are correctly still at Y=0. (And then deleted the C glyph because the Ç glyph is already in the font and has the same shape.)

Regarding the other two fonts I made: there are many tables which can be in a font, and most browsers ignore most of those tables (which isn't a bug; it just means they don't get extra fancy stuff). It appears that none of the browsers use the "bsln" table nor the "BASE" table (WebKit doesn't even claim to use them, but I can't speak for the other browser vendors). Testing browsers using a mechanism which isn't claimed to be supported anywhere would be a mistake.

I would be thrilled to know if other browsers claim to use these baseline tables. If they do, we can test with these two fonts with the additional baseline tables. Otherwise, testing with them would be meaningless.

Thanks,
Myles
