3384	Preserve volume per-vertex colors in sessions	goddard@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        Darwin-19.5.0-x86_64-i386-64bit
ChimeraX Version: 1.1.dev202006100038 (2020-06-10 00:38:38 UTC)
Description
Session saving does not preserve volume per-vertex coloring when that coloring was computed by sampling another map which was closed before saving the session.  The session should remember the per-vertex colors if it is not possible to recompute them.
