# The <code>text_box</code> method accepts both <code>:width</code> and
# <code>:height</code> options. So what happens if the text doesn't fit the box?
#
# The default behavior is to truncate the text but this can be changed with
# the <code>:overflow</code> option. Available modes are <code>:expand</code>
# (the box will increase to fit the text) and <code>:shrink_to_fit</code>
# (the text font size will be shrunk to fit).
#
# If <code>:shrink_to_fit</code> mode is used with the
# <code>:min_font_size</code> option set. The font size will not be reduced to
# less than the value provided even if it means truncating some text.
