Better testing methods for Liberation Fonts?

Hi, For the quality testing on liberation-fonts in the progress of full source hosting on fedorahosted.org, I have performed some tests mentioned in this bug: https://bugzilla.redhat.com/show_bug.cgi?id=444392 As the screenshots attached there, there are some horizontal displacements on certain glyphs. I also manually tested in GIMP on the PSD files which having two versions of font overlapping each other. However, it might be excellent if any of you could provide some better ideas on the testing? Thank you very much. Best Regards, Caius Chance. -- CAIUS CHANCE | CCHANCE AT REDHAT DOT COM X8116 | SW ENG | ENG-I18N | RED HAT APAC APAC DOT REDHAT DOT COM SLASH DISCLAIMER
