code: function( smooth, mipmap, miplinear ){
      var gl = this.gl;
      var filter = getFilter( !!smooth, !!mipmap, !!miplinear);
      gl.texParameteri( T2D, gl.TEXTURE_MAG_FILTER, getFilter( !!smooth, false, false ) );
      gl.texParameteri( T2D, gl.TEXTURE_MIN_FILTER, filter );
    }
docs: Change the filtering parameters
  @param {boolean} [smooth=false]    if true, use LINEAR filtering
  @param {boolean} [mipmap=false]    if true, enable mipmaping
  @param {boolean} [miplinear=false] if true, use linear Mipmapping
