Fix documentation image printing under new development code Printed images are now clipped to image size rather than to papersize of 8.5x11 Images are scaled to 4 inches and centered in display pdf printing is sub-optimal as texi2pdf picks the png rendering (bitmap) rather than the pdf rendering (vector).

      subroutine xscnrm2 (n, x, incx, retval)
      real scnrm2, retval
      complex x(*)
      integer n, incx
      retval = scnrm2 (n, x, incx)
      return
      end
