[x3d-public] allowing animation of Cone, Cylinder bottom/side/top

[Don Brutzman]

Primitive geometry fields are typically defined by dimensions with accessType initializeOnly to avoid possible cost of re-tessellation at run time.

Cone and Cylinder tessellation must be computed similarly regardless of whether bottom, side or top geometry is displayed.

Allowing authors to animate these fields is a valuable animation technique that has no run-time performance issues.

Recommend allowing accessType inputOutput for these fields.
