Expected Behavior

Running validator https://validator.w3.org on basic <picture> elements as per setup config should not result in errors.

Current Behavior

Currently when running validator on:

<picture class="lozad" style="display: block; min-height: 1rem" data-iesrc="images/thumbs/04.jpg" data-alt="">
    <source srcset="images/thumbs/04.jpg" media="(min-width: 1280px)">
   

SVG will very likely take a little longer to render than a base64-encoded raster image. And the Gaussian Blur applied to the simple SVG shapes created by Primitive is probably quite CPU intensive.

Let's run a series of performance tests, ideally on WPT, to compare LQIP raster image rendering performance vs. SQIP rendering performance and also compare CPU utilization.

The value of allowed undershoot in the resize mode ExactOrSmaller is currently a compile time constant. It would be great to make this configurable for the developer using the library:

众所周知，淘宝的IP接口很久之前挂了。
./application/index/controller/admin/Images.php #Line 136
原接口

更新后的接口

好吧，才发现第一个加个accessKey也可以

dalao别摸鱼啦，快来更新，等一个v1.6.2版本。
