- *
- * - if open_wb_window is zero no console window
- * will be opened.
- *
- * - if default_wb_window points to a valid string
- * it will be used to open the window.
- *
- * - if everything fails, read the icon file,
- * scan it for a "WINDOW" tool type and take
- * the corresponding tool type entry string
- * (somewhat primitive if compared to the Macintosh
- * way of doing it...).
- *
- * This routine will return TRUE if it was able to
- * open an output file, FALSE otherwise.
