Improved color scale for falsecolor output. + +Added threshold test for Fresnel approximation to prevent its use +on smooth surfaces with unrealistically low specularities (less than 1.8%). +Water has a specular reflectance of 2.1% at room temperture. + +Removed NICE macro settings in rpict and rtrace, which was slowing down +the processes under Mac OS X (10.4) by about 60% due to processor napping. + +Made xform, replmarks and rad2mgf handle quoted modifiers and names properly. + +Fixed problem in genblinds, where it was generating slats that were too +wide with the +/-r option. (Thanks to Helena Buelow-Huebe for discovering +this bug.) + +Fixed bug in ra_ppm for 16-bit/sample i/o, where it was getting the byte +order wrong (apparently). + +Added -V option to rtcontrib to report actual contributions, rather than +just ray coefficients. + +Fixed bug in ranimate that caused it to fail in continuation of renderings. + +Renamed librt.a to librtrad.a, to avoid conflict on Solaris. Almost +everything now gets linked to -lrtrad instead of -lrt. + +Fixed problem with large sample sets, so -u+ option now is truly random. +Thanks to Rick Mistrick and Younju Yoon for identifying this problem, +which was related to a poorly designed hash function. + +Changed -u+ to be the default setting in rtrace (only). + +Fixed binary i/o for rlam and vwrays under Windows.
