| 16 | * Presently, a lot of graphics programs do not restore the contents of | |

| 18 | * will lose support for PIO_FONTRESET. Note that many font operations are | |
| 19 | * not likely to work with these programs anyway; they need to be | |
| 20 | * fixed. The linux/Documentation directory includes a code snippet | |
| 21 | * to save and restore the text font. | |
