Public Types
using	SceneToPixel = std::function< QPointF(const QPointF &)>
	Map scene point → device pixel, supplied by the canvas.

Public Member Functions
	MeshProfileOverlay ()=default
void	setPolyline (const QVector< QPointF > &scenePolyline)
	Set the persistent profile polyline (scene coords). Rebuilds the chainage table used for chainage↔point mapping.
void	setArrowChainage (double chainage)
	Position the arrow at chainage (scene units along the path). A negative value hides the arrow.
void	paint (QPainter &p, const SceneToPixel &toPixel) const
	Draw the casing + colored line + position arrow in widget/pixel space. Called by MapCanvas::paintEvent after the QSG mesh composite so the profile sits on top of every map layer.
double	totalLength () const
QPointF	chainageToScene (double chainage) const
double	nearestChainage (const QPointF &scenePt) const
	Chainage of the point on the polyline closest to scenePt (orthogonal projection). Used by the map drag tool.
