Chapter 13 // Exercise 13 - Principles & Practice Using C++

In this exercise I am using Visual Studio 2017 and the graphics files found here:

Chapter 13 // Exercise 13

Draw the colour matrix from section 13.10, but without lines around each colour.

For this one, I simply set the line visibility to false. I remember having to change this function as it wasn't working properly so make sure to grab an updated copy of the graphics.h and graphics.cpp from a newer exercise.
