This reverts commit r538 for the moment. In order to roll Chrome to include some bug fixes, I want to land it in between this revert, and the revert revert. That way the baseline changes from the other revisions can be considered without conflating the huge number of changes due to r538. git-svn-id: http://skia.googlecode.com/svn/trunk@560 2bbb7eff-a529-9590-31e7-b0007b416f81
