72aec87047 Add SSSE3-based blur implementation.
Calculations are done on integer, rather than floating point numbers,
so this implementation is not as accurate (but when scale factor is
reasonable enough, no artifacs are visible).
It is, however, faster by a factor of ~3.

fb5dbbe661 Add SSE2-optimized blur.
About 4-6 times faster than naive implementation.

ade9a20788 Isolate blur implementation to a function.
This will allow easier switching between naive/SSE2/AVX implementations.
