Give deep samples the colour of a flat image: each sample's rgb =
colour.rgb * sample alpha / the deep image's flattened alpha, so the recoloured deep
flattens back to the colour image (times the deep coverage). target_input_alpha also scales
the sample alphas towards the colour image's alpha (an approximation: flattening is not
linear in alpha). Python per-sample loop in this first cut (max_samples).
