[eqbeudyj] Vector animation and 3D

Vector graphics can conveniently be rendered at arbitrary resolution.  Extend the idea to vector animations which can be rendered at arbitrary resolution and frame rate.

Of interest is when the animated scene is of a 3D cartoon world (similar in spirit to the the 2D cartoon worlds of vector graphics images).  The vector animation file format relies on 3D graphics primitives, e.g., camera motion, surface reflectance properties.  (All these things already exist.)
