Re: [ft-devel] [patch] emboldening rework v1

Alexei,


thanks for working on this; I fear I won't have more time in the near
future to give more thoughts to the problem.

Just a minor remark:

There is a difference between `cannot be determined' (by the used
algorithm) and `is undetermined' (in the mathematical sense).  I think
FreeType only refers to the former, even if the implementation doesn't
work as expected.
