The reason it never showed up +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 +undiscovered (at least to my knowledge) for over a decade. I think +Bruce Walter of Cornell may have known about it, but I never heard +the details of his discovery. + +Enabled the -p option for primary conversion without tone-mapping +in ra_bmp. Also provides for XYZE input conversion to RGB. + +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. + +Fixed bug in rcalc where it sometimes wasn't parsing the input format +correctly.
