Families: File size benefit of VF

[clairelindsey]

Google Roboto VF And “single file” for existing family Show menu of instances of weights, widths and italics of a style and file size diff. via interactive pie chart, number of styles used vs download load

VF bar static and other grows as you select styles (from roboto classic)

For computing the real-world size difference, I grabbed Roboto TTFs from Google Fonts, and Roboto-VF from its repo, and subset them all to Latin1. The size comparison isn't quite as hot as I was hoping:

Roboto-VF is the size of 7+ single styles. BUT the VF does include the slnt axis, so it covers the Italic styles as well.

As far as I know, the more subsetting we do the less file saving there is/are.

Well, the full Roboto-VF.ttf is 3.4MB, which didn't seem like a great advertisement! Though it has a lot more glyphs than the standard Roboto TTFs downloaded from Google Fonts. So a secondary reason for the subsetting was to make sure everything was working from the same character set. I could try a larger subset if you think that would be a better example.

@chrissam42 this is great! A few things re styling. Could you add the family names under the bars? Maybe something like this:

And if its not a total pain, could you give a little more leading for the list? Seems a tad tight to me.
