[WWcvs] pg: Added a Point context that is a copy of the Vector context.

[dpvc v. a. <we...@ma...>]

Log Message:
-----------
Added a Point context that is a copy of the Vector context.  This will
allow users to override some settings in Vector context (namely, how
they are entered and displayed) without preventing users from being
able to enter points (in Point context).
