-// TSFTextStore is used to interact with the input method via TSF manager.
-// TSFTextStore have a string buffer which is manipulated by TSF manager through
-// ITextStoreACP interface methods such as SetText().
-// When the input method updates the composition, TSFTextStore calls
-// TextInputClient::SetCompositionText(). And when the input method finishes the
-// composition, TSFTextStore calls TextInputClient::InsertText() and clears the
-// buffer.
-//
-// How TSFTextStore works:
-//  - The user enters "a".
-//    - The input method set composition as "a".
-//    - TSF manager calls TSFTextStore::RequestLock().
-//    - TSFTextStore callbacks ITextStoreACPSink::OnLockGranted().
-//    - In OnLockGranted(), TSF manager calls
-//      - TSFTextStore::OnStartComposition()
-//      - TSFTextStore::SetText()
-//        The string buffer is set as "a".
-//      - TSFTextStore::OnUpdateComposition()
-//      - TSFTextStore::OnEndEdit()
-//        TSFTextStore can get the composition information such as underlines.
-//   - TSFTextStore calls TextInputClient::SetCompositionText().
-//     "a" is shown with an underline as composition string.
-// - The user enters <space>.
-//    - The input method set composition as "A".
-//    - TSF manager calls TSFTextStore::RequestLock().
-//    - TSFTextStore callbacks ITextStoreACPSink::OnLockGranted().
-//    - In OnLockGranted(), TSF manager calls
-//      - TSFTextStore::SetText()
-//        The string buffer is set as "A".
-//      - TSFTextStore::OnUpdateComposition()
-//      - TSFTextStore::OnEndEdit()
-//   - TSFTextStore calls TextInputClient::SetCompositionText().
-//     "A" is shown with an underline as composition string.
-// - The user enters <enter>.
-//    - The input method commits "A".
-//    - TSF manager calls TSFTextStore::RequestLock().
-//    - TSFTextStore callbacks ITextStoreACPSink::OnLockGranted().
-//    - In OnLockGranted(), TSF manager calls
-//      - TSFTextStore::OnEndComposition()
-//      - TSFTextStore::OnEndEdit()
-//        TSFTextStore knows "A" is committed.
-//   - TSFTextStore calls TextInputClient::InsertText().
-//     "A" is shown as committed string.
-//   - TSFTextStore clears the string buffer.
-//   - TSFTextStore calls OnSelectionChange(), OnLayoutChange() and
-//     OnTextChange() of ITextStoreACPSink to let TSF manager know that the
-//     string buffer has been changed.
-//
-// About the locking scheme:
-// When TSF manager manipulates the string buffer it calls RequestLock() to get
-// the lock of the document. If TSFTextStore can grant the lock request, it
-// callbacks ITextStoreACPSink::OnLockGranted().
-// RequestLock() is called from only one thread, but called recursively in
-// OnLockGranted() or OnSelectionChange() or OnLayoutChange() or OnTextChange().
-// If the document is locked and the lock request is asynchronous, TSFTextStore
-// queues the request. The queued requests will be handled after the current
-// lock is removed.
-// More information about document locks can be found here:
-//   http://msdn.microsoft.com/en-us/library/ms538064
