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.)
