     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 (WSDISPLAY_FONTORDER_L2R or
     48  * WSDISPLAY_FONTORDER_R2L).
     49  *
     50  * Example:
     51  *
     52  *	struct wsdisplay_font *font;
     53  *	int cookie;
     54  *
     55  *	if ((cookie = wsfont_find(NULL, 8, 16, 0, 0)) <= 0)
     56  *		panic("unable to get 8x16 font");
     57  *
     58  *	if (wsfont_lock(cookie, &font, WSFONT_L2R, WSFONT_R2L) <= 0)
     59  *		panic("unable to lock font");
     60  *
     61  *	... do stuff ...
     62  *
     63  *	wsfont_unlock(cookie);
