I thought of this, but the images would probably be too ugly for IE6 users to be acceptable. Remember, we're talking about making things uglier for 15% of our users (everyone who uses IE6 on math articles) for the benefit of well under 1% of our users (the ones who view equations on non-white backgrounds in non-IE6 browsers). That's just not a reasonable tradeoff. Either it has to be demonstrated that IE6 PNG transparency fixes perform well even on pages with lots of equations, or people will just have to manually adjust background colors if they really care. I've whitelisted \definecolor and \pagecolor in r59550. I'm resolving bug 8 as LATER, and suggest it only be reopened when either IE6 reaches <1% market share, or it can be demonstrated that we can do transparency without significantly hurting IE6 users' experience when reading math articles. _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
