Message : [truetype] Make `IUP' gvar deltas do the same as Apple (#50832). When points are not touched by gvar interpolation deltas, FreeType gave a slightly different result than Apple's CoreText. The OpenType working group will update the specification to document the following behaviour: If the two points with deltas to the `left' and `right' of the untouched point have the same coordinate, then the inferred delta for the untouched point should be zero. * src/truetype/ttgxvar.c (tt_delta_interpolate): Implement new behaviour.
