/* <Description> */
/* Computes the exact bounding box of an outline. This is slower */
/* than computing the control box. However, it uses an advanced */
/* algorithm which returns _very_ quickly when the two boxes */
/* coincide. Otherwise, the outline Bezier arcs are walked over to */
/* extract their extrema. */

/* FreeType error code. 0 means success. */
