# The base unit in Prawn is the PDF Point. One PDF Point is equal to 1/72 of
# an inch.
#
# There is no need to waste time converting this measures. Prawn provides
# helpers for converting from other measurements
# to PDF Points.
#
# Just <code>require "prawn/measurement_extensions"</code> and it will mix some
# helpers onto <code>Numeric</code> for converting common measurement units to
# PDF Points.
