THESE ARE UNSCHEDULED BACKLOG TASKS
-----------------------------------
+* Cache objects. These are proper non-geometric geometry database
+ objects intended to store binary results that have a dependency on
+ other object(s). A named hash (e.g. md5) is recorded for each
+ dependent object along with the computed results.
+
+ Three potential candidates for leveraging cache objects are 1) prep
+ objects containing the final prepped state of a given object
+ hierarchy (particularly useful for BoT and BREP geometry), 2)
+ raytrace objects containing the intersection results for a given
+ view (i.e., a grid of primary rays), and 3) rtgl point samples
+ (which is a variant of 2 but potentially view independent).
+
* investigate OpenEXR (BSD licensed HDE image format)
* the 'cp' command no longer draws the object that was copied --
