-----------
+* raytracing rhc crashes (inside malloc, so previous memory badness)
+ with normal tolerance set to non-default value (e.g. tol norm 0.1);
+ also fails (non-crash) if absolute tolerance is changed (e.g., tol
+ abs 0.1)

* revolve raytracing seems to be busted.. at least with the example
csgbrep revolve shape

-----------------------------------
+* investigate why epa primitive is so sensitive to coarse absolute
+ value changes (run csgbrep, tol abs=1, facetize and get 321k poly)

* implement a new "simulate" command for applying physics deformations
to geometry. Each timestep (default steps==1) would get recorded as
new geometry unless updating the existing is requested. Usage might
