* Name: nxtk_setposition
*
* Description:
* Set the position for the selected client window. This position does not
* include the offsets for the borders nor for any toolbar. Those offsets
* will be added in to set the full window position.
*
* Input Parameters:
* hfwnd - The window handle returned by nxtk_openwindow
* pos - The new position of the client sub-window
*
* Returned Value:
* OK on success; ERROR on failure with errno set appropriately
*
