/* FT_Get_Outline_BBox */
/* */
/* <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. */
/* */
/* <Input> */
/* outline :: A pointer to the source outline. */
/* */
/* <Output> */
/* bbox :: The outline's exact bounding box. */
/* */
/* <Return> */
/* Error code. 0 means success. */
