Chapter 6 - Phong.frag, missing clamp call

[ghost]

When discussing the Phong.fragshader the book mentions using clamp to limit the Phong RGB components to the 0.0-1.0 range.

The actual clamp call seems to be missing from the shader code, however:

Adding this, the visual result is markedly different:

 Phong = clamp(Phong, 0.0, 1.0);

Good catch, I actually don't remember whether that's intentional or if it was a mistake!
