This class is an interface to graphics context objects, which interpret drawing commands based on a number of attributes that make up an environment for rendering. NSGraphicsContext can be used change a number of rendering options, such as whether or not antialiasing should be done, or whether image smoothing and interpolation should be used when drawing images.
