* Consider Case: * When defulat option has {left: 0, width: 100}, and we set {right: 0} * through setOption or media query, using normal zrUtil.merge will cause * {right: 0} does not take effect. * * @example * ComponentModel.extend({ * init: function () { * ... * var in

(targetOption, newOption, opt)

 *  that width (or height) should not be calculated by left and right (or top and bottom).
