 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.)
