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