Issue description

以滑块设置cssfilter不生效，必须滚动一下或者放大缩小，重绘瓦片才会变化。如何重绘layer？

Please provide a reproduction URL (on any jsfiddle like site)

褐色:{{sepia}}<el-slider v-model="sepia" :min="0" :max="1" :step="0.01" @change="setCssFilterConfig"> 透明度:{{opacity}}<el-slider v-model="opacity" :min="0" :max="1" :step="0.01" @change="setCssFilterConfig">

setCssFilterConfig(){ const a = this.map.getBaseLayer() a.setOptions({cssFilter: sepia(${this.sepia}) opacity(${this.opacity})}) }

the method is config

layer.config({....})

用layer.config({....})问题已解决，什么情况下用setOptions呢？
