Win metrics causing clipping

[m4rc1e]

Hey,

The Win Metrics are causing clipping in Window's applications. The spec is a rather interesting read for these values. At GF it is policy to make the win Ascent and win Descent the ymin, ymax of the font's bbox. I've peiced together a quick glyphsapp script to report the ymin, ymax in Glyphsapp for a source file.

Remember that radically changing these values may upset users and cause their documents to overflow. I can write more on this soonish.

Cheers,
Marc

I suggest making the change even if it is disruptive for users because clipping or cutting off essential parts of the letters is never going to get better for readers of those glyphs, but a little reflow can be worked around 😄

Thank you @m4rc1e for pointing this out and @davelab6 for weighing in. We will review and determine the appropriate revisions to make for this.

I'm okay for reflow also; almost all of our uses are purely as webfonts with pretty robust layout rules.

Fixed! New versions are on the way.
