* @param min_agree minimal number of channels to agree on a point (real number to work with fuzzy averages) (3.0)
* @param weights scales for R,B,G {0.294118, 0.117647, 0.588235}
* @param dust_remove do not reduce average weight when only one image differs much from the average (true)
* @param keep_weights return channel weights after A in RGBA (was removed)
* @param keep_weights return channel weights after A in RGBA (was removed). Now (11/12/2022): +1 - old meaning, +2 - replace port_weights with channel imclt
* @param texture_rbg_stride output stride for overlapped texture in floats, or 0 to skip
