Which Win API will make their font metrics identical to OS X's?

I have taken a sophomoric glance at openType (and some of this might apply to trueType). It specifies (for example) three ways to calculate vertical leading: the right way, the Windows way and the Mac way. The latter two are there for "compatibility" reasons. This is complicated by the indication that the Windows way is sometimes used to detect overlap.


This is only a trivial part of the whole problem, but I would expect that it would be possible to get font table info in either OS. Perhaps some uniform calculations can then be made for some metric values.

I have no idea how useful those metics would be in writing to the screen and the printer using interesting (eg. unicode friendly) APIs.

Just babbling.
