## Pots a 2D shape defined by piecewise smooth polynomials in the current axis.
##
## @var{pp} is a cell where each elements is a 2-by-(poly_degree+1) matrix
## containing a pair of polynomials.
## @var{N} is the number of points to be used in non-straight edges.
## Additional parameter value pairs are passed to @code{drawPolygon}.
