First of all, the ft2demos release are *always* tied to the 
corresponding freetype2 one, which means that
we do not guarantee that ft2demos 2.1.10 would build or work correctly 
with anything other than
FreeType 2.1.10

I guarantee you that this is not the first time that a new release of 
the font engine broke the build of a previous
version of the demo programs. This is purely intentional, since we also 
use the demo programs to experiment
a bit (e.g. with the cache sub-system, or with the hint algorithms, etc...).

That's also why we always release both packages at the same time, with 
the same version numbers.

We changed the function signature because it was inconsistent with the 
rest of the API[1], and we know of no library or
program that uses the stroker at the moment (except ft2demos), mainly 
because this component was still highly
experimental and had some important bugs anyway. That is, until now 
(i.e. it is now stable and part of the public API)

We thus estimate that this will create zero problems. However, if you 
can name a single Debian package, except ft2demos
that relies on the stroker, I'll accept to postpone the release a few 
days to revert the signature and provide an alternative
function that takes a FT_Library instead.

[1] Yes, I know the API isn't very consistent anyway, but let's not add 
oil to the fire...
