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