# To produce this manual we use the <code>stroke_axis</code> helper method
# within the examples.
#
# <code>stroke_axis</code> prints the x and y axis for the current bounding box
# with markers in 100 increments. The defaults can be changed with various
# options.
#
# Note that the examples define a custom <code>:height</code> option so that
# only the example canvas is used (as seen with the output of the first line of
# the example code).
