random variate from power exponential distribution: performances

[Brian Gough]

The source code for exppow.c says 

    "Scale factor chosen by upper bound on ratio at b = infinity.
     This could be improved by using a rational function
     approximation to the bounding curve. "

Maybe that would help improve the rejection method?
