 Changed marksources() routine (src/rt/source.c) to check all

 the first.  This permits sources to be described with intervening

 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.
+
+Made similar change for virtual sources to allow modifiers and aliases
+on the mirror and prism types to work properly.
