Werner,
Not sure i understand 100%, but isn't it significant that the infinality
patched freetype only renders ttfautohinted fonts in this way? An
infinality patched freetype (bug or not) renders other instructed
truetype fonts perfectly normally afaik.

Well, Erik tries to implement Greg's ClearType
Many thanks for this Erik,
You seem to have recreated the glitchy rendering that earlier versions of
ttfautohint created on iOS and when adobe apps converted ttfautohinted fonts to
outlines. That's very interesting i think, as it probably points to something
important still going on.

Today I tested out the TT-instructed Oxygen font from the KDE repo
with my TT subpixel hinting patches. This is the result:

This looks like Oxygen has been hinted with an older version of
ttfautohint which was buggy... Current
First though i think we should check that the issue is not with a
particular buggy build of Oxygen;
FYI: Recent versions of ttfautohint add version information and
calling parameters to the `name' table; older ones don't.

I 've sent Erik ttfautohint 0.8 versions of Oxygen to confirm the problem.

Hi Vernon / Werner,
I tried it out with the version of Oxygen you sent me, with similar
results. I was also able to view it in Windows XP, and as I thought it
renders fine there (although they filter the hell out of it).

Erik,
thanks for your analysis.
(The main difference between #2 and #3 is that #3 snaps horizontal
stems to pixel boundaries, which normal Freetype slight hinting does
not do. I personally prefer the stems to be snapped to integer
pixels like this. It looks less dirty to me, however
Thanks Werner. I'd definitely be curious to know how the MS rasterizer
determines when to/not use backwards compatibility mode. As of right
now, my patches have no way of automatically determining this, and I'd
like to go from using a hard-coded list of font names to something more
dynamic!
Erik,
Are you testing the rendering via web browsers only? Or do you get same results
with e.g. ftview?

I've only been using browsers for these, but AFAIK it *should* be the
same. :)

Ok, so i've tested this with a infinality patched freetype 2.4.9 w Kubuntu.
Using ftview or the system font viewer any truetype font instructed with
ttfautohint (i'm using 0.8) renders as Erik has shown. Pretty much the
same screwed up rendering that we saw with old versions of ttfautohint w

Obviously a bug w.r.t. Erik's implementation of ClearType's
compatibility mode. I've contacted Greg Hitchcock, asking for
clarification.

Yikes!!! After examining the TT instructions in the instructed version
of the Oxygen fonts, it
