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