Summary: The ability to use pre-determined character widths will benefit alternative layout engines such as gagern's canvas layout engine. I would also like to experiment would using CSS transforms to absolutely position each glyph. This diff adds a new make rule, make extended_metrics, which generates metrics that also containing glyph widths. Test Plan: - run `make extended_metrics` - verify that fontMetricsData.js contains entries with 5 numbers instead of 4 Reviewers: emily alpert
