Oprofile log with current algorithm

Basically scrolling identi.ca automatically in epiphany for some time (big blur under the main box in that page)

FEGaussianBlur::apply 8.16% percent of the time
                      6.68% of the time in the blur algorithm

It is that fast because it is using tiling to create the shadow from a small one.
