Hi Nikolaus,

This looks good!

Question: I see the extra weight is applied only to the right hand side of the 
vstems. Is this because of the way the emboldening function works? Have you 
noticed any issues with the sub-pixel translation that this causes? (I don't 
think so, and they are unhinted anyway)

Thanks.

-Dave

 Very nice, thanks!  Unfortunately, I currently don't have sufficient
time to review the code; probably in the beginning of October.

Sure, what matters is that it finds its' way to master and to the masses 
eventually :) I'll test out Dave's 300,250,250,0 parameters in the mean time 
and maybe look at the TrueType driver.

I'm currently dogfooding the darkener without gamma correction (software pixman 
is too slow...) and find that text isn't much uglier than usual using lcdlight, 
so it may be possible to enable this by default without too many complaints 
from unsuspecting users.

I was thinking about writing an announcement article or something if you release a 
version with the darkener to explain why it's done, what users should know (lcdlight!) 
and why distro maintainers and drawing-library-developers should care. I hope this would 
increase acceptance and maybe (attention: wishful thinking) some collective impulse to 
improve things instead of "MY FONTS LOOK DIFFERENT YOU ANUSES". Maybe even a 
longer article that explains the font and font rendering situation on Linux and what 
should be done to improve it, to publish it on LWN.net and/or the German c't. I'll see.

For now, I'll bask in the glory of emboldened but not gamma-corrected glyphs.
