Re: [ft-devel] State of autohinter stem darkening

[Nikolaus Waxweiler]

I fixed the excessive emboldening bug by modifying the last step of 
computing the emboldening amount: divide by the emRatio, as 
FT_Outline_EmboldenXY or at least emboldening inside the autohinter 
apparently depends on the units per EM of the font. This also fixed 
something else: fonts with units per EM below 1000 were emboldened 
excessively, above 1000 were emboldened too lightly.

I think the code can be reviewed now. Werner? :)
