// Creates a multi-avatar image from `images` based on the amount of them:
// * For 0 the default avatar is returned.
// * For 1 the only image is fully displayed.
// * For 2 images are split between the left and the right half.
// * For 3 one image is on the left half, other two are split horizontally on
//   the right half.
// * For 4 each image takes a quarter.
// * For 5 and more handling is as in the previous point, but the bottom-right
//   quarter displays how many more images are apart from the ones displayed.
