IJ1 has special case code for convolve3x3() on a ByteProcessor. IJ2 code was adapted from ShortProcessor and FloatProcessor. As it stands 8-bit convolutions are not the same between IJ1 & IJ2. As an example run Sharpen on a sample image such as Bridge in the two programs and see the differences.

Further testing showed it was broken for 8 and 16 bit data. Only correct for float. Fixed convolution oriented plugins and find edges to work like IJ1. Fixed in e728eefe2ebb11a9530bf2a8b8d44ce8bb27d091.
