Fog drawing information for use in GLKit rendering effects.

These properties are specifically designed to mimic the fog calculations provided by OpenGL ES 1.1.
When fog is enabled, the fog component is calculated and clamped to a range from
1.0. Then, the fog value is used as a blending factor between the computed fragment color and the fog color.
A Boolean value that indicates whether fog is applied to the fragment color.
Choosing the Fog Mode
The algorithm used to compute the density of the fog applied to the fragment color.
The color of the fog at maximum density.
The rate at which the fog exponent increases.
The minimum distance in eye coordinates before fog is applied to the fragment color.
The distance in eye coordinates where fog completely covers the color fragment.
A mode that describes how the fog component is calculated for the fragment.
