LinearFilter returns the weighted average of the four texture elements that are closest to the specified texture coordinates,
and can include items wrapped or repeated from other parts of a texture,
depending on the values of THREE.Texture.wrapS | wrapS and THREE.Texture.wrapT | wrapT, and on the exact mapping.
