  clip-path: inset-rectangle(from top, from right, from bottom, from left, rounded-x, rounded-y)
  /* Looks like this is what rect() used to be like with clip */
  /* Will replace inset(), I suppose */
 
  clip-path: polygon(a, bunch, of, points)
  clip-path: circle(radius at x, y)
  clip-path: ellipse(radius-x, radius-y at x, y)
 
}
