Liberation 2.0 Vs Liberation 1.0 (Need comments)

[pravin.d.s at gmail.com]

Hi All,

  As you know Liberation 2.0 is one of the feature of Fedora 18. Recent
analysis and comparison with Liberation 1 it is more clear that final
output of Liberation 2.0 is not as sharp as it was with Liberation 1.0.
Though both are from same vendor (Ascender Corporation) hinting bytecodes
are different.

  Liberation2 already available in Fedora18 Beta, if one wants to install
both fonts simultaneously Download [1]  has liberation ttf with different
family name, so one can have both version same time on Fedora. (cp to
/usr/share/fonts/liberation and then fc-cache)

 https://bugzilla.redhat.com/show_bug.cgi?id=856239 ,  though bugzilla has
more than 100 comments but if someone see to the attached screenshot will
be sufficient for review.

 I did comparison of Fedora output with Windows7 as well. But on Windows
results are totally different than Fedora.

 On Fedora 18 :

(Here Sans2 = Liberation2 , San1 = Liberation1 and Arimo = Google Croscore)

 On Windows7 :

 On Fedora 18 :

freetype-freeworld Xft.antialias: 1 Xft.dpi: 96 Xft.hinting: 1
*Xft.hintstyle: hintslight* Xft.lcdfilter: lcddefault *Xft.rgba: rgb*)

 In last 4 comments Mike Fabian has given even more better screenshot
showing hinting bytecode which actually affects final output.

 Problem is subjectivity of hinting output, each users has different
opinion. So just thinking whether we should defer this feature and once
Liberation2 output matches with Liberation1 then only we can go with this
feature.

Thanks & Regards,
