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).
