In this case, the type of pixelArray->data() is unsigned char.
It means we can avoid calling of SET function.

And I measured the spent time of before and after patching when visit http://www.w3.org/TR/filter-effects/examples/feComponentTransfer.svg.

Before adopting this patch, the function spent 190(ms).
After patching, it spent only 35(ms).
So this could reduce 80% of spent time.

Below is about testing environment.
OS: Ubuntu 12.04 64bit
CPU: Intel Core i7-3770 CPU @ 3.40GHz
Memory: 8,123,696 kB
