# The <code>font</code> method can be used in three different ways.
#
# If we don't pass it any arguments it will return the current font being used
# to render text.
#
# If we just pass it a font name it will use that font for rendering text
# through the rest of the document.
#
# It can also be used by passing a font name and a block. In this case the
# specified font will only be used to render text inside the block.
