However, something about the fix in 1.14.2 is breaking glyph rendering through CairoSVG on the latest OS X. So it seems that the new APIs were not implemented quite correctly.

There was 5 months between the release of 1.14.0 and the release of 1.14.2, so I expect many more changes were made than just the half dozen lines changed in moving to this modern API. I would not suspect this particular change of having caused the problem you're having.

You're right; I'm sorry for hijacking your thread.
