@ Instantiate a vertical filter function for filtering a 4 pixels wide
@ slice. The first half of the registers contain one row, while the second
@ half of a register contains the second-next row (also stored in the first
@ half of the register two steps ahead). The convolution does two outputs
@ at a time; the output of q5-q12 into one, and q4-q13 into another one.
@ The first half of first output is the first output row, the first half
@ of the other output is the second output row. The second halves of the
@ registers are rows 3 and 4.
@ This only is designed to work for 4 or 8 output lines.
