Message:

Attempting to support stacking of images when they are read piecemeal (scan by scan). Need to specify size of the (original) image, so that normalisation can be done (during convolution) when the image size is not the original image size. Doing some algebraic gymnastics in the pixel rejection to account for the image being smaller than the original.
