/*
* wsfont_find() can be called with any of the parameters as 0, meaning we
* don't care about that aspect of the font. It returns a cookie which
* we can use with the other functions. When more flexibility is required,
* wsfont_enum() should be used. The last two parameters to wsfont_lock()
* are the bit order and byte order required (WSDISPLAY_FONTORDER_L2R or
* WSDISPLAY_FONTORDER_R2L).
*
* Example:
*
* struct wsdisplay_font *font;
* int cookie;
*
* if ((cookie = wsfont_find(NULL, 8, 16, 0, 0)) <= 0)
* panic("unable to get 8x16 font");
*
* if (wsfont_lock(cookie, &font, WSDISPLAY_FONTORDER_L2R,
* WSDISPLAY_FONTORDER_R2L) <= 0)
* panic("unable to lock font");
*
* ... do stuff ...
*
* wsfont_unlock(cookie);
