Functions
double	meshkit::plan::ringSignedArea (const Polygon &ring)
	Compute oriented shoelace area after translating corners to the first vertex.
Polygon	meshkit::plan::normalizeRingCCW (const Polygon &ring)
	Copy a ring while dropping scale-fuzzy consecutive/closing duplicates and reversing negative area.
bool	meshkit::plan::polylineIntersectsRect (const Vector< Point2 > &path, const Box2 &rect)
	Test whether any consecutive path segment meets a normalized closed rectangle.
bool	meshkit::plan::pointInRegion (const Polygon &ring, const Vector< Polygon > &holes, const Point2 &p)
	Combine outer-ring parity with exclusion by every supplied hole-ring parity.
bool	meshkit::plan::pointInRing (const Polygon &ring, const Point2 &p)
	Test a point using a strict horizontal-ray odd-even crossing rule.
bool	meshkit::plan::ringIsSimple (const Polygon &ring)
	Reject proper nonadjacent edge crossings using plain double orientation signs.
double	meshkit::plan::ringTurnDeg (const Polygon &ring, int i)
	Compute a signed exterior turn at one ring corner using adjacent edge cross/dot products.
Text	meshkit::plan::validateQuadRegion (const QuadRegion &r, const Vector< Polygon > &domains, const Vector< Polygon > &holes)
	Check region authoring policy, normalized ring and sampled domain/hole containment.
Text	meshkit::plan::validateQuadRegionsDisjoint (const Vector< QuadRegion > &regions)
	Check explicit region pairs for proper crossings or strictly interior sampled vertices.
QuadRegionMode	meshkit::plan::classifyQuadRegion (const Polygon &ring, Vector< int > *corners, double cornerTolDeg=25.0, double rectilinearTolDeg=2.0)
	Heuristically classify normalized ring turns as Mapped, Submapped or Free.
Polygon	meshkit::plan::resampleRing (const Polygon &ring, double h, double keepTurnDeg=0.0)
	Normalize a ring and insert equal-part subdivisions along all implicit closing edges.
