I made some measurements.
The average acceleration of SVG filters is approx 3%.
This is very little, doesn't cause considerable acceleration.
In addition, I tested the platformTransformColorSpace() function,
so I queried the time at the begin and at the end of this function
and compared the runtime of the original code and the modified code.
The result of this (function only) test in the best case is
 ~312sec for the original code
 ~281sec for the optimalized code
This is also too little.
I hoped the 3% speed-up enough to apply the patch and
I think that it is not possible to accelerate it better.
