 Currently they include only those collected by Tom Goddard (focus on
 density maps, molecular assemblies, electron microscopy).

+<b>Document volume and surface programming interfaces</b><br>
+November 12, 2010<br>
+Tom Goddard<br>
+Include documentation in the code of useful volume and surface Python
+and C++ functions and generate documentation from those code comments.
+This would speed up my new development that uses existing code, would
+encourage me to make more thoughtful interfaces to algorithms, and
+substantially encourage outside developers.

+<b>Surface rendering in Python</b><br>
+November 12, 2010<br>
+Tom Goddard<br>
+Port surface rendering code from C++ to Python using PyOpenGL.
+Most surface rendering code (excluding transparent rendering) does not
+require C++ for speed.  Keep only the speed critical part in C++.
+This would enable easier development of new surface features such as
+clipped outline boxes, or separate inside/outside colors.

+<b>Solid volume rendering in Python</b><br>
+November 12, 2010<br>
+Tom Goddard<br>
+Port solid volume rendering code from C++ to Python using PyOpenGL.
+I don't think any part of the existing code requires C++ for speed.
+In Python it would be easier to add new capabilities like clipped
+outline boxes.

+<b>Volume slice tool</b><br>
+November 12, 2010<br>
+Tom Goddard<br>
+Allow displaying opaque gray-level volume slices on oblique slices when
+clipping a volume with near/far or per-model clip planes.  The 3d volume
+and an clipped outline box of the volume would still be shown to provide
+context.  Moving the slice would be done by moving the clip plane.  Might
+also allow click and drag on the cut facet.  Currently oblique slices can
+be shown with the volume dialog subregion selection panel.  That method has
+several difficulties: not able to find it, moving slice is not intuitive,
+context provided by seeing volume behind slice and box outline not provided.

+<b>Clipped outline boxes</b><br>
+November 12, 2010<br>
+Tom Goddard<br>
+When a volume surface or solid model outline box is clipped with near/far
+or per-model clip planes show the outline at the clip plane.  Currently the
+outline is simply clipped.  Showing the outline would provide a good visual
+cue as to where the clipping is done, especially with solid volume rendering.
