Quick: Support reparenting
To support reparenting, we make the compositing surface independent of the window by using gfx::TEXTURE_TRANSPORT. We also need to be able to keep frame data across window changes so we can reconstruct the QSGNode tree in a new context, so extract that data into DelegatedFrameNodeData class. Any context-specific data is still stored in DelegatedFrameNode. Also hook up window changes to WebContents::WasShown/Hidden for Quick. Remove checking of Qt isVisible state, this mechanism is used to sync Chromium with Qt, not the other way around. WasShown/Hidden is orthogonal to Show/Hide, and can use different triggers. However for Widgets it probably makes sense to hook both up to widget visibility. Change-Id: I1ef4b50cd61b8e54b791e03f0b41929c42fec8bf Reviewed-by: Jocelyn Turcotte <>
