Seems the deltas specified in TTFStems have no impact in DirectWrite? Is this a bug, or unavoidable, or intentional? I just spent a long time figuring out why it does not seem to work “any more” (because my testing environment has changed, not because Glyphs has changed).
I definitely need them in DirectWrite as well, otherwise there are px sizes in which the Regular and Bold have the same y thickness and they become almost impossible to distinguish. So, for me, controlling the stem thicknesses at each px size is crucial. In the Regular and Bold, the jumps to the next px thickness should be fairly synchronised.
Zone deltas work in DirectWrite, and normal point-based deltas also work. Why not TTFStems deltas?
