It's called "internal" for a reason ;)

Complex problem, we draw together all the letters that have the same "x adjustement",
i.e. those that we can draw together in a WYSIWYG way. After some letters the
calculation of the hi-res position gives a different adjustement, i.e. we need to start
drawing the "s" (in your case) one pixel more to the left or the right than it would
be if it was painted together with the rest.

Maybe with Xft2 we can have real font zooming and we wouldn't need this ugly 
mechanism anymore...
