# The <code>font_size</code> method works just like the <code>font</code>
# method.
#
# In fact we can even use <code>font</code> with the <code>:size</code> option
# to declare which size we want.
#
# Another way to change the font size is by supplying the <code>:size</code>
# option to the text methods.
#
# The default font size is <code>12</code>.
