[ft] Strange rendering/alignment of dot of the 'exclamation' of Consolas font using subpixel.

[Kazuo Teramoto]

Hi
I'm using freetype 2.3.5 to render Consolas font (by Lucas de Groot
(bundled in Vista...)).

But I'm experiencing a strange behavior in the rendering of '!'. The
rendering is wrong when subpixel is on, take a look at this two
pictures from konsole (kde4) and gvim:
http://socrates.if.usp.br/~kazuo/gvim_consolas_exclamation.png (Consolas 8pt)
http://socrates.if.usp.br/~kazuo/konsole_consolas_exclamation.png (Consolas 8pt)

See? The exclamation mark is off by one pixel to the left, but look at
this other Consolas at 15pt on konsole:
http://socrates.if.usp.br/~kazuo/konsole_consolas_15_exclamation.png

This is off by one pixel to the right. Now if I try with ftview (look
like it don't use subpixel) all is aligned:
http://socrates.if.usp.br/~kazuo/ftview_consolas_exclamation.png

If I disable subpixel all come aligned too. So I thought  this is a/an
bug/error/my mistake config/Consolas-related-bug in the subpixel
rendering of Consolas exclamations fonts (all other chars is good
including the interrogation '?') but when I use xfd or xterm the
exclamation is aligned, look at a xterm sample:
http://socrates.if.usp.br/~kazuo/xterm_consolas_exclamation.png

It is aligned! The only 'font system' difference I spot on xterm and
konsole/gvim is that my xterm link to Xft lib and konsole/gvim don't.

I don't know if this is really a problem with freetype, I don't know
much about the rendering system. But I thought that someone on this
list that know more about font rendering on linux can help me to find
the origin of this problem, and if is this really a bug, report it to
the correct people.

My fontconfig config is:
autohint=true
rgba=rgb
hinting=true
hintstyle=hintmedium
antialias=true

Thanks,
Kazuo Teramoto
