Eliminate the use of a tmp buffer for image blur

Because the blur_one_direction routine, only reads the
source buffer once for each result, it can be used to
blur inplace. This allows the code to avoid using
a temporary buffer for the intermediate result.

This produces the same pixels according to skdiff, and
has the same speed.
