RGComputeBoundingBox
Determines the endpoints of a rectangle in the complex plane that contains the region. 
Synopsis
#include "slepcrg.h" 
PetscErrorCode RGComputeBoundingBox(RG rg,PetscReal *a,PetscReal *b,PetscReal *c,PetscReal *d)
Not Collective
Input Parameter
Output Parameters
|  | a | - left endpoint of the bounding box in the real axis | 
|  | b | - right endpoint of the bounding box in the real axis | 
|  | c | - bottom endpoint of the bounding box in the imaginary axis | 
|  | d | - top endpoint of the bounding box in the imaginary axis | 
Notes
The bounding box is defined as [a,b]x[c,d]. In regions that are not bounded (e.g. an
open interval) or with the complement flag set, it makes no sense to compute a bounding
box, so the return values are infinite.
