Lobotomized FontMetrics for TUI displays. TUI supports multiple fonts, but all are the same size. It is often possible to support simple size variations. For instance, a double high font could be implemented with 2 font banks - top part and bottom part. Some TUI hardware can set specific lines to double high or double wide. This does not fit into the window model and could only be used in a device specific manner. Typical TUI displays have from 2 - 4 128 char font banks. The Link terminals used by BMS have 4 banks. EGA/VGA text mode on PC's also has 4 banks. Software text mode emulation under Windows or OS/2, however, has only 2 banks which are hardwired to the IBMPC charset.
