Allocate memory. This will use b2Alloc if the size is larger than b2_maxBlockSize.
void b2CollideEdgeAndPolygon(b2Manifold *manifold, const b2EdgeShape *edgeA, const b2Transform &xfA, const b2PolygonShape *polygonB, const b2Transform &xfB)
Compute the collision manifold between an edge and a circle.
