          Severity: Normal

WebImage is used to take page snapshots. Currently a snapshot can be drawn in WebProcess and used by UIProcess. With enabling GPUProcess for rendering, the snapshot will be recorded in WebProcess, drawn in GPUProcess and used in UIProcess. This will require replacing the ShareableBitmap in WebImage by ImageBuffer.
