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