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