    convolve test: validate 1D filters are 1D · 04c24078

    Since the 8-tap lowpass filter is non-interpolating, the results are
    different between applying it at whole-pel values and not. This
    means that 1D-only versions are requried to be implemented, as
    opposed to being an optimization of the 2D case. Calling the 2D
    filter instead of the horizontal-only filter is not equivalent
    in this case. Update the test to pass invalid filters to the
    unused stage of the 1D-only calls, to verify they're unused.
