Adjusting Tessellation Geometry Amplification Due Monday, October 1, at 5:00 PM

Start with the demo from class, called "tess" in the class examples area. Adjust the TCS so that a detailed sphere made up of little triangles is drawn. Remove the normalization from the TES, so that a cube is drawn instead of a sphere. Next, scale the locations like this: 
        control_closeness = maximum influence of a single control point, taken from gl_TessCoord
        Instead of normalizing the lengths of the vectors to each point, scale them by control_closeness instead.
