 Fixed problem with rpict where it was drawing illum sources badly
 even when they weren't all that small in the view.
+
+Added in(i) function to rcalc for more flexible channel evaluation.
+
+Replaced all calls to vfork() with regular fork() calls.
+
+Fixed bug in glarendx for dgr calculation with sources behind view.
+
+Added -p option to histo to print percentages/percentiles r.t. counts.
+
+Added a source occluder cache to accelerate shadow testing.  This
+can save up to 50% of the calculation time in scenes with many
+light sources, especially ones containing large occluders.  This
+optimization may be tuned or switched off with the -DSHADCACHE=N
+compile switch, where N is the resolution of the shadow cache, or
+0 to disable it.  Since this is purely a time vs. memory trade-off,
+I decided not to make it a new command-line option.  (We already
+have plenty.)
+
+****** COMPATIBILITY CHANGE ********
+Changed the following command names to avoid conflicts:
+	rview -> rvu (with symbolic link back to rview)
+	calc -> icalc
+	lam -> rlam
+	gencat -> gencatenary
+
+Improved -f option of normpat, which caused odd color changes before.
+
+Created pgblur script which does fast Gaussian blur of image without changing
+its dimensions.  This is very useful in certain types of image processing
+calculations, such as finding or removing low frequencies.
+
+****** COMPATIBILITY CHANGE ********
+Changed little-used objpict script so that it takes scene files rather than
+rpict options on the command line, and puts everything into the right
+coordinate position automatically rather than requiring the user to do it.
+
+Added -I option to replmarks for mesh instancing.
