Re: [ft-devel] ttfautohint 0.4 has been released

heh van Dalen's TruetypeViewer is what i used to check the fonts :) 
Nothing *that* glitchy shows.

Microsoft's implementation of truetype rendering seems to never cause these 
problems.
It's a specific Apple implementation of Truetype to postscript/screen rendering 
that seems to be the issue. What does iOS, Adobe CS OSX apps, and OSX 
postscript printing have in common? Oh and the old Cleartype TT previewer in 
Fontlab - ttfautohint fonts were shredded in that too, but again, only in OSX 
if i remember correctly.
