When indicates magnification,
the value assigned to ` TEXTURE_MAG_FILTER` determines how the texture
value is obtained.
There are two possible values for ` TEXTURE_MAG_FILTER`:
` NEAREST` and ` LINEAR`.
` NEAREST` behaves exactly as ` NEAREST` for
` TEXTURE_MIN_FILTER`
(equation 3.13 and 3.14 are used);
` LINEAR` behaves exactly as ` LINEAR` for
` TEXTURE_MIN_FILTER` (equation 3.15 is used).
The level-of-detail 0 texture array is always used for magnification.

Finally,
there is the choice of **c**,
the minification vs. magnification switch-over point.
If the magnification filter is given by ` LINEAR` and
the minification filter is given by ` NEAREST_MIPMAP_NEAREST`
or ` NEAREST_MIPMAP_LINEAR`,
then .
This is done to ensure that a minified texture does not appear
``sharper'' than a magnified texture.
Otherwise **c = 0**.
