# Whenever the <code>text_box</code> method truncates text, this truncated bit
# is not lost, it is the method return value and we can take advantage of that.
#
# We just need to take some precautions.

# This example renders as much of the text as will fit in a larger font inside
# one text_box and then proceeds to render the remaining text in the default
# size in a second text_box.
