# frozen_string_literal: true
# We've already seen one way of using text boxes with the <code>text_box</code>
# method. Turns out this method is just a convenience for using the
# <code>Prawn::Text::Box</code> class as it creates a new object and call
# <code>render</code> on it.
#
# Knowing that any extensions we add to <code>Prawn::Text::Box</code> will take
# effect when we use the <code>text_box</code> method. To add an extension all
# we need to do is append the <code>Prawn::Text::Box.extensions</code> array
# with a module.
