/// @details
/// - A quad is a triangle pair represented using 4 vertex indices v0, v1,
/// v2, v3.
/// The first triangle is made out of indices v0, v1, v3 and the second triangle
/// from indices v2, v3, v1. The piecewise linear barycentric u/v parametrization
/// of the quad is defined as:
/// - (u=0, v=0) at v0,
/// - (u=1, v=0) at v1,
/// - (u=0, v=1) at v3, and
/// - (u=1, v=1) at v2
/// This is achieved by correcting the u'/v' coordinates of the second
/// triangle by
/// *u = 1-u'* and *v = 1-v'*, yielding a piecewise linear parametrization.
