            Bug ID: 249785
           Summary: Hook up
                    willStartRenderingUpdateDisplay/didCompleteRenderingUp
                    dateDisplay for WC
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

In bug 249750/258248 at 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.
