feat(physics): 16 - a rock's own shape: phys_convex (Jolt's convex hull of a point cloud) and phys_scaled (one hull, every rock of that shape at its own size); the libraries rebuilt on the Mac and the PC (still KERNEL32 alone); hull_shape_test holds the scale and that a yaw turns a body the way a renderer turns an instance
