Thanks :)

I just saw that Markus Trippelsdorf posted two patches to this list for 
Qt5 and Skia to enable proper blending. It was even on by default in Qt5 
when someone complained that fonts looked different and too thin 
compared to what other toolkits rendered, so they reverted the change on 
XCB[1]. Funny how many pieces of the puzzle are just laying around 
without much communication between the involved parties.

It looks like the potential for change is there, it's just that stem 
darkening for non-CFF and autohinted fonts needs to be in place first 
before the toolkits consider enabling it. I'll have a look around to see 
if I can maybe salvage something.

Regards,
Nikolaus

PS: I converted the Liberation Sans family to .otf and hinted them with 
AFDKO. Looks nice, but has some vertical spacing issues:
