Here are some design criteria carried over from issue #27.

Emphasize that a point has no part. For example:
- No partial occlusion, even when the point representation (presumably disk or sphere) is only partially shaded by a surface
A point that lies on a positive-codimension entity is never occluded by its neighborhood in that entity (but might be occluded by some region of that entity not containing it, such as a point on the "back" hemisphere of a sphere being occluded by its "front" hemisphere).

The bare-bones display in pull request #82 draws points in an arbitrary order over the rest of the scene. Points should eventually occlude each other based on distance and be occluded by other elements. Here are some design criteria carried over from issue #27. 1. Emphasize that a point has no part. For example: - No partial occlusion, even when the point representation (presumably disk or sphere) is only partially shaded by a surface 2. A point that lies on a positive-codimension entity is never occluded by its neighborhood in that entity (but might be occluded by some region of that entity not containing it, such as a point on the "back" hemisphere of a sphere being occluded by its "front" hemisphere).
