Comment 1 Mike FABIAN 2009-02-02 05:13:42 UTC 
This is just a workaround but as no fix seems to be in sight
in freetype2, it might be useful to use this workaround
in the fontconfig configuration.

Makes sense to me.  Keith?

    [conf] Disable hinting when emboldening (#19904)
    
    Hinting will be done before Embolden in freetype2,
    but in such case, Embolden will get wrong result
    on some glyph contours after applying hinting.
    Actually, hinting should be done after embolden, but we can't
    fix it in current freetype2. So as a workaround, just turn off
    hinting if we want to do embolden.

The patch has caused bug 20599.  This better be decided on a font by font basis.  I'm removing from my tree.  Lets close as notabug and submit per-font config as new bugs.
