title: Make a Single Word Within a String Bold
body: <p>Given the following code (from this answer: <a href="https://stackoverflow.com/questions/20842801/how-to-display-text-in-pygame">How to display text in pygame?</a>):</p>
  <pre><code>pygame.font.init() # you have to call this at the start, 
                     # if you want to use this module.
  my_font = pygame.font.SysFont('Comic Sans MS', 30)
  text_surface = my_font.render('Some Text', False, (0, 0, 0))
  </code></pre>
  <p>Is it possible to make the word 'Text' bold while keeping the word 'Some ' regular?</p>
  <p>(without rendering multiple times)</p>
