     34  * wsfont_find() can be called with any of the parameters as 0, meaning we
     35  * don't care about that aspect of the font. It returns a cookie which
     36  * we can use with the other functions. When more flexibility is required,
     37  * wsfont_enum() should be used. The last two parameters to wsfont_lock()
     38  * are the bit order and byte order required (WSFONT_L2R or WSFONT_R2L).
     39  *
     40  * Example:
     41  *
     42  *	struct wsdisplay_font *font;
     43  *	int cookie;
     44  *
     45  *	if ((cookie = wsfont_find(NULL, 8, 16, 0, 0)) < 0)
     46  *		panic("unable to get 8x16 font");
     47  *
     48  *	if (wsfont_lock(cookie, &font, WSFONT_L2R, WSFONT_R2L) < 0)
     49  *		panic("unable to lock font");
     50  *
     51  *	... do stuff ...
     52  *
     53  *	wsfont_unlock(cookie);
