+ REGRESSION (PSON): White or Black flash occurs when process swapping on navigation on iOS
+ https://bugs.webkit.org/show_bug.cgi?id=189695
+ <rdar://problem/44551146>
+
+ Reviewed by Simon Fraser.
+
+ Freeze the layers on UI process side during process swap.
+
+ * UIProcess/API/Cocoa/WKWebView.mm:
+ (-[WKWebView _processWillChange]):
+
+ Shared work of _processWillSwap and _processDidExit.
+
+ (-[WKWebView _processWillSwap]):
+ (-[WKWebView _processDidExit]):
+
+ Split into two functions. Don't reset scroll position and similar when doing navigation swap.
+
+ * UIProcess/API/Cocoa/WKWebViewInternal.h:
+ * UIProcess/RemoteLayerTree/RemoteLayerTreeDrawingAreaProxy.h:
+ * UIProcess/RemoteLayerTree/RemoteLayerTreeDrawingAreaProxy.mm:
+ (WebKit::RemoteLayerTreeDrawingAreaProxy::RemoteLayerTreeDrawingAreaProxy):
+ (WebKit::RemoteLayerTreeDrawingAreaProxy::detachRemoteLayerTreeHost):
+
+ Add to way to detach RemoteLayerTreeHost from the drawing area. Inert RemoteLayerTreeHost will host
+ the frozen layers.
+
+ (WebKit::RemoteLayerTreeDrawingAreaProxy::commitLayerTree):
+ (WebKit::RemoteLayerTreeDrawingAreaProxy::updateDebugIndicator):
+ (WebKit::RemoteLayerTreeDrawingAreaProxy::hideContentUntilPendingUpdate):

+ (WebKit::RemoteLayerTreeHost::updateLayerTree):
+ (WebKit::RemoteLayerTreeHost::animationDidStart):
+ (WebKit::RemoteLayerTreeHost::animationDidEnd):
+ (WebKit::RemoteLayerTreeHost::detachFromDrawingArea):
+
+ Clear the DrawingArea backpointer.
+
+ * UIProcess/WebPageProxy.cpp:
+ (WebKit::WebPageProxy::continueNavigationInNewProcess):
+ (WebKit::WebPageProxy::resetState):
+
+ Detach and save the current RemoteLayerTreeHost on navigation swap.
+
+ * UIProcess/WebPageProxy.h:
+ * UIProcess/ios/PageClientImplIOS.mm:
+ (WebKit::PageClientImpl::processWillSwap):
+
+ Avoid reseting the scroll position.
+
+ * UIProcess/ios/WebPageProxyIOS.mm:
+ (WebKit::WebPageProxy::setAcceleratedCompositingRootLayer):
+
+ Drop the frozen layers after setting the new root layer.
+
+ * UIProcess/mac/WebPageProxyMac.mm:
+ (WebKit::WebPageProxy::setAcceleratedCompositingRootLayer):
+
+ For completeness do this also on Mac (where remote layers are currently not used).
