Checking Vertical Metric Linegaps.
Check ID: <FontBakeryCheck:com.google.fonts/check/linegaps>
The LineGap value is a space added to the line height created by the union of the (typo/hhea)Ascender and (typo/hhea)Descender. It is handled differently according to the environment.
This leading value will be added above the text line in most desktop apps. It will be shared above and under in web browsers, and ignored in Windows if Use_Typo_Metrics is disabled.
For better linespacing consistency across platforms, (typo/hhea)LineGap values must be 0.
Overridden: This check was originally a WARN but was overridden by the ufo profile: For Google Fonts, all messages from this check are considered FAILs.
