Description Simon Fraser (smfr) 2022-12-22 10:04:54 PST 
In bug 249750/258248@main I added Page:: willStartRenderingUpdateDisplay() and Page:: didCompleteRenderingUpdateDisplay(), which get called before and after the painting phase and compositing phase of a rendering update. These are used to drive web inspector's "Composite" timeline events, and will also be used for other things soon.

WebKit2 clients can call these via the same-named functions on WebPage.

These need hooking up for WC, at the DrawingArea level.
