The separable blur algorithm gives +45% on SampleBlur, +84% on SampleBigBlur, +31% on TheVerge, +35 to +85% on blurbench in HQ (depending on size), +8 to +35% in low quality. (All of these on 32bit MacPro). Review URL: https://codereview.appspot.com/6851117 git-svn-id: http://skia.googlecode.com/svn/trunk@6601 2bbb7eff-a529-9590-31e7-b0007b416f81
