Dear Jean-Baptiste Kempf, if I knew how to implement what Steinar wish
I would do
it already. Clearly there is big miss-understanding here.

Steinar could implement such filter already if he knew how to do it.
I think he does not know that he does not know that algorithm.

The only thing I could propose which would make filter faster under
same parameters
is to cache all results of atan2f / sqrtf calls.

About radial blur center issues, i think Steinar is confusing radial
blur with zoom blur.
