Detailed Description

GraphicsSystem handles the Graphics of the Engine.

The idea behind creating an abstract class would be to allow for different Graphic API's to handle how images are drawn. For example, change from OpenGL to DirectX easily.

This is the class that knows how to draw images on the screen.
