/* When pretend_empty_preedit is set to TRUE,
* gtk_im_context_ime_get_preedit_string() will return an empty string
* instead of the actual content of ImmGetCompositionStringW().
*
* This is necessary because GtkEntry expects the preedit buffer to be
* cleared before commit() is called, otherwise it leads to an assertion
* failure in Pango. However, since we emit the commit() signal while
* handling the WM_IME_COMPOSITION message, the IME buffer will be non-empty,
* so we temporarily set this flag while emmiting the appropriate signals.
