Code review comment for lp:~victored/unity/fixes

Nice fix to the ugly truth that launcher-icons with and even height can't center-line align with the tooltips. Works as advertised.

I'm good to merge that into unity trunk, but I need to know if you've signed the Canonical contributor-agreement. If you haven't done yet so please follow the procedure described here: https://wiki.canonical.com/LegalServices/Forms/ContributorAgreement

Thanks in advance!
