hmm... tables.. great idea!
an average user won't use bigger outline than 2-3 pixels, it means in
average 5x5==25 pixels per matrix. so precalculating that matrix for 256
possible value of 'src' will be ~6kb, fit into the cache and saves us from
doing 
          const int tmp= (src*mp[mx] + 128)>>8;
instead we could do
	  const int tmp= mp[mx];

anyway i don't know if it will speed up at all.

anyway it's now 3 times faster than blur, so time to check how to speedup
blur now ;)

i thought it's a commandline parameter but now checked and you're right it's
constant...
