I think I should work a bit more on it, in my tests some cases there is
still 3% speed loss.
Usualy it occurs when the vertical filter size is ~1 so it processes one
line at a time. I think
if we process lines in "batches"  it can be improved. But it is more
complex to implement
because for example there is filters which skips some lines, and the memory
required will
be increased.
