Looking at ImageTexture and TextureProperties, it's unclear to me how to set up properties.
How to specify magnificationFilter & minificationFilter to be linear?
<transform scale="1.01 1.01 1.01">
<shape>
<sphere></sphere>
<appearance>
<ImageTexture url="texture.png"></ImageTexture>
</appearance>
</shape>
</transform>
<ImageTexture url="texture.png">
<TextureProperties generateMipMaps='TRUE' minificationFilter='LINEAR' magnificationFilter='LINEAR'></TextureProperties>
</ImageTexture >
