  23  * Notes:
  24  *  The normal flow for IMM/IME Processing is as follows.
  25  * 1) The Keyboard Driver generates key messages which are first passed to
  26  *    the IMM and then to IME via ImeProcessKey. If the IME returns 0  then
  27  *    it does not want the key and the keyboard driver then generates the
  28  *    WM_KEYUP/WM_KEYDOWN messages.  However if the IME is going to process the
  29  *    key it returns non-zero.
  30  * 2) If the IME is going to process the key then the IMM calls ImeToAsciiEx to
  31  *    process the key.  the IME modifies the HIMC structure to reflect the
  32  *    current state and generates any messages it needs the IMM to process.
  33  * 3) IMM checks the messages and send them to the application in question. From
  34  *    here the IMM level deals with if the application is IME aware or not.
