### Question:
TierDimensions implements Serializable { static List<TierDimensions> buildPrimeTierDimensionsList(final Bounds roughStackFullScaleBounds, final int maxPixelsPerDimension, final int numberOfTiers) { final List<TierDimensions> list = new ArrayList<>(); Bounds parentStackFullScaleBounds = roughStackFullScaleBounds; for (int tier = 0; tier < numberOfTiers; tier++) { final TierDimensions tierDimensions = buildPrimeSplitTier(parentStackFullScaleBounds, maxPixelsPerDimension, tier); list.add(tierDimensions); parentStackFullScaleBounds = tierDimensions.getFullScaleBounds(); } LOG.info("buildPrimeTierDimensionsList: returning dimensions for {} tiers", list.size()); return list; } private  TierDimensions(final int fullScaleCellWidth,
