 before is because I always closed processes in the reverse order
 of opening them in other programs.  I went through and found similar
 (potential) bugs in the rview device subprocess code and util/netproc.c.

+Corrected the normalization of the Gaussian reflectance model.  This will
+cause an increase in specularity for low-lying light sources.
+Thanks to Don Walters of Boeing and Arne Duer of the Univ. of Innsbruck
+for pointing out this error.  The square root used for the two cosines
+in the denominator of the normalization factor should not be present.
+This was a serious mistake I made in the original model, which went

+Enabled the -p option for primary conversion without tone-mapping

+Fixed what I consider a bug in pvalue -o when taking XYZE files on input,
+where it was inappropriately undoing the exposure value so that it always
+reported radiance rather than XYZ values with Y in cd/m^2.
+
+Made it so ra_bmp only produces run-length encoded 8-bit output for
+grayscale images that are tone-mapped.  This minimizes circumstances
+under which output scanline order is reversed.
