IBrowserHostImeSetComposition Method

Begins a new composition or updates the existing composition. Blink has a special node (a composition node) that allows the input method to change text without affecting other DOM nodes. This method may be called multiple times as the composition changes. When the client is done making changes the composition should either be canceled or completed. To cancel the composition call ImeCancelComposition. To complete the composition call either ImeCommitText or ImeFinishComposingText. Completion is usually signaled when: The client receives a WM_IME_COMPOSITION message with a GCS_RESULTSTR flag (on Windows). This method is only used when window rendering is disabled. (WPF and OffScreen)
