[Fontconfig] Synthetic Emboldening and Blurriness

[Erik]

An issue I have noticed with the synthetic emboldening is that the upper 
parts of glyphs are not hinted properly;  i.e. there is blurriness in 
the vertical direction.  From testing, it appears that this only affects 
antialiased fonts, which makes sense.  From digging around online, I 
read that this is possibly because freetype is hinting prior to the 
emboldening step.  Is there currently a way to get the desired effect 
(no blurriness) and still have antialiasing enabled?
