DRAWSEGMENT, S_POLYGON shape: remove useless copies or conversion to std::vector<wxPoint> of SHPE_POLY_SET polygon shape.

Rename GetPolyPoint() to BuildPolyPointsList(), because GetPolyPoint() looks like an accessor, but it is not an accessor.
(Using it as accessor can creates a *very long calculation time* for very basic access to polygon vertices)
