# Partitioners (in the code the short form parter is used) take
# care of calculating appropriate tick positions for a given axis
# range. Automatic partitioners create several tick lists, which are
# rated by an axis rater instance afterwards while manual partitioners
# create a single tick list only, which thus doesn't need to be rated.
#
# Note that the partitioning uses fractional number arithmetics. For
# that, tick instances can be initialized with floats using a fixed
# precision but also with strings as shown.
