Variable fonts report incorrect version

[lordsutch]

Describe the bug
In the Inter-3.10.zip archive, the variable fonts report a version of "1.0.0;git-src" rather than "3.010;git-aca7606f2" as shown by the other OpenType/TrueType font files. This makes it difficult to tell if the installed versions of the variable fonts are out of date.

It appears that the updateFontVersion() call in VarFontProject._build_interpolatable_masters() at https://github.com/rsms/inter/blob/master/misc/fontbuild#L185 does not have the intended effect of updating the version information in the variable font.

To Reproduce
Steps to reproduce the behavior (at a command line):

1. Run (e.g.) otfinfo -v Inter\ (OTF)/Inter-Italic.otf
2. Run (e.g.) otfinfo -v Inter\ (TTF\ variable)/Inter-italic.var.ttf

Expected behavior
Both otfinfo commands should show the same output: "Version 3.010;git-aca7606f2"

Environment

• OS: macOS 10.14.6 - but this should be OS-agnostic
• Version of font: 3.10 (3.010;git-aca7606f2)

Thank you. This is a know bug in the latest release. It’s due to changes to a library that the build toolchain uses and we’re working on a fix.

This was a regression introduced in a recent upgrade of one of the 3rd party libraries used by fontbuild (fontmake).

Here is a build from master as is at the time of writing this comment.
