Programming Notes
=================   

   The background is rendered with 2 TLVertex (screen space) triangles. The sprites
   are defined as an array of user defined type that is a container for sprite properties
   such as position, direction, speed and size. Each of the sprites is rendered as 2
   TLVertex triangles each frame.
