If the GPU process crashes while a screen pixels request is outstanding, then currently that request will never be completed. This patch makes it so that we check for outstanding requests when the compositor is (re)initialized, and send those requests to the new compositor if they exist. This includes a refactoring of how the LayerViewSupport class accesses the UiCompositorControllerChild from the UI thread. Previously it looked it up through the nsWindow's mCompositorSession whenever it was required. However, since the compositor session can now be destroyed and created we instead notify the UI thread whenever that occurs with LayerViewSupport::NotifyCompositorSessionLost and LayerViewSupport::NotifyCompositorCreated. The latter of these takes a reference to the UiCompositorControllerChild, which can safely be used by the LayerViewSupport on the UI thread.

// Destroy to indirectly call DisposeNative here also solves 5), by

// making everything go through the UI thread, avoiding contention.

// pending event that we had shut down. In that case the event bails

|
// and does not touch mWindow.
|

//
|
|
// 4) happens through DisposeNative directly.
|

|
// and only make a pending call if the destroyed flag is not set.
|

|
|
