I wonder why the results for sub-pixel-hinting differ between
Freetype 2.1.10 and Freetype 2.2.1.20061027 (CVS from 2006-10-27).
The byte code interpreter is compiled in in both versions
of freetype.
Here are two screen shots:

(Luxi Mono is just an arbitrary example, it seems to happen with all
fonts).
In the ft-2.1.10 screen shot, the vertical lines are solid black. In
the ft-2.2.1.20061027 screen shot, all the vertical lines have light
blue shadow at the right side.
This is easy to see when enlarging with "xmag", but I can see that
easily already without enlarging while reading text with
sub-pixel-hinting rendered by ft-2.2.1.20061027. Looks strange to me.
Is that a bug or is this light blue shadow there on purpose?
