Source/WebKit/chromium:

The chromium side of this landed at r178256 and seems stable.

* public/WebWidget.h:
(WebKit::WebWidget::setCompositorSurfaceReady):
* src/WebViewImpl.cpp:
(WebKit::WebViewImpl::WebViewImpl):
(WebKit::WebViewImpl::~WebViewImpl):
(WebKit):
(WebKit::WebViewImpl::setIsTransparent):
(WebKit::WebViewImpl::setIsAcceleratedCompositingActive):
* src/WebViewImpl.h:
* tests/ScrollingCoordinatorChromiumTest.cpp:
(WebKit::FakeWebViewClient::initializeLayerTreeView):
(FakeWebViewClient):
(WebKit::FakeWebViewClient::layerTreeView):
(WebKit::ScrollingCoordinatorChromiumTest::ScrollingCoordinatorChromiumTest):
(ScrollingCoordinatorChromiumTest):

Tools:

WebWidgetClient has to support the new compositor initialization path.

* DumpRenderTree/chromium/WebViewHost.cpp:
(WebViewHost::initializeLayerTreeView):
(WebViewHost::setWebWidget):
