* CFS_RECT: we still use the ptCurrentPos as a starting point and our

* window is only as large as we need for the string, but we do not
|
|
* grow such that our window exceeds the given rect. Wrapping if

* needed and possible. If our ptCurrentPos is outside of our rect
|
|
* then no window is displayed.
|
|
* CFS_FORCE_POSITION: appears to behave just like CFS_POINT
|
|
* maybe because the default MSIME does not do any IME adjusting.
