# Horizontal text alignment can be achieved by supplying the <code>:align</code> option
# to the text methods. Available options are <code>:left</code>,
# <code>:right</code>, <code>:center</code>, and <code>:justify</code>, with
# <code>:left</code> as default.
#
# Vertical text alignment can be achieved using the <code>:valign</code> option
# with the text methods. Available options are <code>:top</code>,
# <code>:center</code>, and <code>:bottom</code>, with <code>:top</code> as
# default.
#
# Both forms of alignment will be evaluated in the context of the current
# bounding_box.
