  22  * Notes:
  23  *  The normal flow for IMM/IME Processing is as follows.
  24  * 1) The Keyboard Driver generates key messages which are first passed to
  25  *    the IMM and then to IME via ImeProcessKey. If the IME returns 0  then
  26  *    it does not want the key and the keyboard driver then generates the
  27  *    WM_KEYUP/WM_KEYDOWN messages.  However if the IME is going to process the
  28  *    key it returns non-zero.
  29  * 2) If the IME is going to process the key then the IMM calls ImeToAsciiEx to
  30  *    process the key.  the IME modifies the HIMC structure to reflect the
  31  *    current state and generates any messages it needs the IMM to process.
  32  * 3) IMM checks the messages and send them to the application in question. From
  33  *    here the IMM level deals with if the application is IME aware or not.
  34  *
  35  *  This flow does not work well for the X11 driver and XIM.
  36  *   (It works fine for Mac)
  37  *  As such we will have to reroute step 1.  Instead the x11drv driver will
  38  *  generate an XIM events and call directly into this IME implementation.
  39  *  As such we will have to use the alternative ImmGenerateMessage path to be
  40  *  generate the messages that we want the IMM layer to send to the application.

1140          * CFS_RECT:  we still use the ptCurrentPos as a starting point and our
1141          *    window is only as large as we need for the string, but we do not
1142          *    grow such that our window exceeds the given rect.  Wrapping if
1143          *    needed and possible.   If our ptCurrentPos is outside of our rect
1144          *    then no window is displayed.
1145          * CFS_FORCE_POSITION: appears to behave just like CFS_POINT
1146          *    maybe because the default MSIME does not do any IME adjusting.
