Why wasn't a ref-test a better solution in this particular case?
Because gaussian blurs on the GPU are not accurate, and look slightly different 
on different GPUs, but usually "close enough".
We need a way to measure "close enough" for features where all you can get is 
"close enough"! Ref-tests and pixel-tests are way to rigid for that, and 
require constant rebaselines and headaches.

There is _NO_ gaussian blur in that patch.
DongSung mentioned gaussian blur in the comment, which is what I was referring 
But other bugs as well, like delegated scrolling, also have that problem of 
results not being 100% the same every time.
