+ * Description:
+ *   Move a rectangular region within the client sub-window of a framed window
+ *
+ * Input Parameters:
+ *   hfwnd   - The client sub-window within which the move is to be done.
+ *            This must have been previously created by nxtk_openwindow().
+ *   rect   - Describes the rectangular region relative to the client
+ *            sub-window to move
+ *   offset - The offset to move the region
+ *
+ * Return:
+ *   OK on success; ERROR on failure with errno set appropriately
