Describe the feature or problem you’d like to solve

Currently, when showing skeletons in a table/collection/scroll view, it feels kinda bad (imho) that user interaction or scrolling is disabled.

Proposed solution

Add some kind of flag to allow views to scroll while skeletons are visible?

Global or per-scroll view?

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.

我不知道是不是我没设置对，我用Storyboard拖了一个Controller，然后加上了TableView和TableViewCell，然后复制了demo里xib的部分代码，运行没有效果，一片白，查看图层是有好多Cell的，但是没有子控件的影子。

I have a very big app and do not want to make a placeholder for each screen I would like to provide context to about what is loading. (And also do not want a general 'loading' message). Is there currently a way to change the title/subtitle easily for each ViewController, from the ViewController itself?
