No, not 5px, five standard deviations.  That was only the test I
wrote, though.  The test Philip wrote tested canvas for a huge range
of blur values, all superimposed, and three out of five browsers
looked correct to me.  Again, they might not actually have identical
RGB values, but close enough that I can't tell easily even if they're
superimposed, let alone side-by-side.
