GSLayer.vertOrigin not exported to UFO

Noticed that the value for GSLayer.vertOrigin is discarded in a .glif file when saved as a UFO on both Glyphs 2 and Glyphs 3. Is this intentional?

As mentioned on GitHub, GSLayer.vertOrigin is designed to be a delta to the default origin, thus the value for public.verticalOrigin should be re-calculated using GSFontMaster.ascender or GSLayer.vertWidth, but I think it’s technically feasible.
