292 * The table below defines up to which height level a particular delta in the legend should be
293 * used. One could opt for just dividing the maximum height and use that as delta, but that
294 * creates many "ugly" legend labels, e.g. once every 950 meter. As a result, this table will
295 * reduce the number of deltas to 7: every 100m, 200m, 300m, 500m, 750m, 1000m and 1250m. The
296 * deltas are closer together at the lower numbers because going from 12 entries to just 4, as
297 * would happen when replacing 200m and 300m by 250m, would mean the legend would be short and
298 * that might not be considered appropriate.
299 *
300 * The current method yields at least 7 legend entries and at most 12. It can be increased to
301 * 8 by adding a 150m and 400m option, but especially 150m creates ugly heights.
302 *
303 * It tries to evenly space the legend items over the two columns that are there for the legend.
