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.
