- Import Greek glyph set designed by Florian Fecher for GSoC 2018. No kerning,
  might need a slight respacing. Imported anyway because someting is better than
  nothing.
- Correct positioning of dotaccentcomb.case.
- Correct mark positioning in caroncomb.case.
- Correct appearance of ustraightstroke in variable font, the overlap became
  visible at smaller, autohinted sizes.
- Correct bar positioning in Ustraightstroke and ustraightstroke
- Correct anchor positioning in Y
- Internal: Consolidate various anchors in composites into the base outline
  glyphs, to reduce the chance they get out sync.
