Log Message:
-----------
* Changed title text to use the small instead of the big font
* Handled title positioning
* Cleaned up the main loop a bit (comments, stylistic changes, shortened some lines, etc)
* Fixed setting the dragon's feet position (the x coordinate should be at the midpoint of the animation)
