Functions
void	openswmm::twoD::buildMeshTopology (MeshData &mesh)
	Build mesh topology and precompute geometry from raw vertex/triangle data.

bool	openswmm::twoD::buildMeshTopologyCancellable (MeshData &mesh, const std::function< bool(int)> &progress)
	Cancellable equivalent; progress receives integer percent and returns true to cancel.

std::string	openswmm::twoD::validateMesh (const MeshData &mesh)
	Validate mesh data for consistency.

std::string	openswmm::twoD::validateMeshCancellable (const MeshData &mesh, const std::function< bool(int)> &progress, bool &cancelled)
	Cancellable validator. `cancelled` is set when progress returns true.

void	openswmm::twoD::recomputeVertexZDependents (MeshData &mesh, int vidx)
	Recompute Z-derived per-triangle / per-edge geometry for triangles incident to a vertex whose Z just changed.

void	openswmm::twoD::recomputeAllZDependents (MeshData &mesh)
	Whole-mesh form of `recomputeVertexZDependents`.

Detailed Description

Implementation of mesh topology construction and geometry computation.

Mixed triangle / quadrilateral cells (kMaxCellVerts = 4 padded layout, see MeshData.hpp). Triangle arithmetic is kept expression-for-expression identical to the triangle-only builder so an all-triangle mesh reproduces its geometry bit-for-bit; quads use the shoelace area and the area-weighted centroid of their two sub-triangles (the vertex mean is NOT the centroid of a skewed quad, and the Perot arms / ghost distances need the real one).
