17 * Presently, a lot of graphics programs do not restore the contents of
18 * the higher font pages. Defining this flag will avoid use of them, but
19 * will lose support for PIO_FONTRESET. Note that many font operations are
20 * not likely to work with these programs anyway; they need to be
21 * fixed. The linux/Documentation directory includes a code snippet
22 * to save and restore the text font.
