/**
* This method exists for the following reason:
*
* <p>The segmenter receives at each frame a cropped image to operate on, depending on the user
* specifying a ROI. It therefore returns spots whose coordinates are with respect to the top-left
* corner of the ROI, not of the original image.
*
* <p>This method modifies the given spots to put them back in the image coordinate system.
* Additionally, is a non-square ROI was specified (e.g. a polygon), it prunes the spots that are
* not within the polygon of the ROI.
*
* @param spotsThisFrame the spot list to inspect
* @param settings the {@link Settings} object that will be used to retrieve the image ROI and
* cropping information
* @return a list of spot. Depending on the presence of a polygon ROI, it might be a new, pruned
* list. Or not.
