+One of the most popular uses for a fragment shader is to calculate beautiful lighting, especially when used with
 a normal map, which will be explained in our Normal Mapping tutorial.  In a framework shader you give an output
 variable that is the final RGBA value.  This is then passed to the OpenGL pipeline to process.  In this tutorial
 we won't be passing in any color but hard coding the triangle to white.  The next tutorial will pass in colors.
