     43  * wsfont_find() can be called with any of the parameters as 0, meaning we
     44  * don't care about that aspect of the font. It returns a cookie which
     45  * we can use with the other functions. When more flexibility is required,
     46  * wsfont_enum() should be used. The last two parameters to wsfont_lock()
     47  * are the bit order and byte order required (WSFONT_LITTLE or WSFONT_BIG).
     48  *
     49  * Example:
     50  *
     51  *	int cookie;
     52  *	struct wsdisplay_font *font;
     53  *
     54  *	if ((cookie = wsfont_find(NULL, 8, 16, 0, 0)) < 0)
     55  *		panic("unable to get 8x16 font");
     56  *
     57  *	if (wsfont_lock(cookie, &font, WSFONT_LITTLE, WSFONT_BIG) < 0)
     58  *		panic("unable to lock font");
     59  *
     60  *	... do stuff ...
     61  *
     62  *	wsfont_unlock(cookie);
