AntiMoron opened a new issue #2055: getComponentRect什么时候出个同步版本
URL: https://github.com/apache/incubator-weex/issues/2055
 
 
   现在的方式都是
   ```javascript
   const dom = weex.requireModule('dom');
   dom.getComponentRect(ref, ({size}) => {
     blabla
   });
   ```
   
实际这个和前端DOM的设计没对齐.在做三端兼容的代码时候体验就不是很好,尤其是多个DOM宽度计算相互依赖的情况下，又要判断DOM有没有又要异步看看结果异步拿到没。正常前端是：
   ```javascript
   [sw, sh] = [dom.scrollWidth, dom.scrollHeight];
   ```
   期待能在结果返回上在同一个call/cc里，如下这样最好：
   ```javascript
   const dom = weex.requireModule('dom');
   const domInfo = dom.getComponentRectSync(ref);
   // domInfo.size.blabla...
   ```
