[Devel] Processing families, ( for David Turner )

[Martin Muskens]

Dear David,

I have a rather urgent problem.

In Freetype, version 1.4 -> 1.5 in pshglob.c You build in the processing of 
families.
My problem is, the with certain scalings, the generated bitmaps are not correct.
I try to display a PostScript file with embedded fonts.

I found that putting in an ABS fixed the problem. But, I am not sure this is 
the correct solution.
Could You check if my fix is correct, and maybe add it to the head?

Thank You.
