// PolyLine.h ... definition of CPolyLine class
//
// A polyline contains one or more contours, where each contour
// is defined by a list of corners and side-styles
// There may be multiple contours in a polyline.
// The last contour may be open or closed, any others must be closed.
// All of the corners and side-styles are concatenated into 2 arrays,
// separated by setting the end_contour flag of the last corner of
// each contour.
//
// When used for copper areas, the first contour is the outer edge
// of the area, subsequent ones are "holes" in the copper.
