I distribute freetype-2 as part of two different packages. The target OS
(EPOC) resolves functions in dll's by ordinal.
If a user upgrades one but not the other, they will have a problem, which
means that I will have a lot of problems.

Therefore I am very much in favour of a new function.

In other words, I cannot afford to move to a Freetype 2 library that is not
backwards compatible.
