# Rotating text is best avoided on free flowing text, so this example
# will only use the <code>text_box</code> method as we can have much more
# control over its output.
#
# To rotate text all we need to do is use the <code>:rotate</code> option
# passing an angle in degrees and an optional <code>:rotate_around</code> to
# indicate the origin of the rotation (the default is <code>:upper_left</code>).
