That's very true. However, cairo aims at constant quality across output targets and has a similar utility in it's testing suite to verify that: http://gitweb.freedesktop.org/?p=cairo;a=tree;h=4bcc292bc335525f804db83f002692fb42a7b7c7;hb=8efb103600e9c034f8652f495d390d6a4178061e;f=test/pdiff So assuming that the layout code produces identical output on all platforms, testing cairo -backed platforms (gtk, win32...) for pixel-perfectness might make sense. -- Kalle Vahlman, [EMAIL PROTECTED] Powered by http://movial.fi Interesting stuff at http://syslog.movial.fi _______________________________________________ webkit-dev mailing list [email protected] http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
