 * <p>A typical pattern is to use SurfaceTexture to render frames to a {@link TextureView}; however,

 * a TextureView is not <i>required</i> for using the texture object. The texture object may be used

 * as part of an OpenGL ES shader.

 * <p>When sampling from the texture one should first transform the texture coordinates using the

 * matrix queried via {@link #getTransformMatrix(float[])}.  The transform matrix may change each

 * time {@link #updateTexImage} is called, so it should be re-queried each time the texture image
