调试后发现是下面这个函数的问题，dpi=2造成后面assets.find找不到资源

建议做一个兼容修改，优先找x2的图片，如果找不到就找 x1的图片

另外我试验了一下，如果强制 let dpi = '/x1/'，图片可以显示，但还是保持图片的原始大小

AssetsManager.getImage = function (name) {
  let anydpi = '/xx/';
  let dpi = '/x‘ + TBrowser.getDevicePixelRatio() + ’/';

  const assets = g_awtk_assets['image'];
  if (assets) {
    const asset = assets.find(iter => {
      return name == iter.name && (iter.uri.indexOf(anydpi) >= 0 || iter.uri.indexOf(dpi) >= 0);;
    });

    return asset;
  }

  return null;
}

一、
git clone https://github.com/emscripten-core/emsdk.git

cd emsdk

./emsdk install latest

./emsdk activate latest

source ./emsdk_env.sh
安装完成。
二、
编译 awtk 本身

git clone https://github.com/zlgopen/awtk.git
cd awtk
scons -j 8
编译完成。

三、
编译 demoui

git clone https://github.com/zlgopen/awtk-web.git
cd awtk-web
python build.py ../awtk/demos/demoui_build.json all

第三步出现以下错误：

请问是否源文件存在错误？
谢谢！

比如应用的尺寸是800x480像素
生成的web应用在手机浏览器上只能显示其中一部分

而且没有滚动条，无法拖动或缩放，可能与手机的高DPI有关系
在电脑上如果DPI是100%，如果浏览器窗口太小是可以有滚动条的

一般web应用都会从服务器获取一些数据，还可能会提交一些表单，这方面awtk-web是怎么做的？
