CoreText, DirectWrite, and FreeType. To summarize the behaviors: FreeType applies (and still applies, need to fix that) the originOffsetY in the wrong direction. FreeType and DirectWrite do not use the lower left of the corresponding 'glyf' entry as the origin. CoreText doesn't recognize 'sbix' fonts without a 'glyf' table (the other two do) and also only provides the bounds of the 'glyf' entry (does not allow for proper repaint if the bitmap extends outside those bounds).

While MSOT issue 191 is closed, and so I expect that wording to arrive in OFF, I thought it would be valuable to file this issue on this repo to track not only this being fixed in OFF, but the 3 implementations (and any others) aligning on the new standard definition of the behavior.
Peter, which are the 3 implementations were you referring to?
