/*
* The vert[] array lists vertices, indexed by binary order of initial axes,
* where X has weight 1, Y weight 2, Z weight 4.
* Initially "min" corresponds to 0, "max" to 1.
* Specifically GeomCreate("bbox", CR_MIN, min, CR_MAX, max) makes a bbox with:
* vert[0] = (min.x, min.y, min.z)
* vert[1] = (max.x, min.y, min.z)
* vert[2] = (min.x, max.y, min.z) ...
* vert[7] = (max.x, max.y, max.z).
* Note this property isn't necessarily preserved if the bbox is transformed.
*/
/* We always use projective coordinates, i.e. min and max are vectors
* of length pdim
