// The Image primitive does not have any special handling for maintaining
// aspect ratio. This example shows that you can provide whatever specific
// behaviour you like.
//
// Here, we extend the "face_fit" example with animation to show how truly
// diverse and usage-specific behaviours are made possible by NOT putting a
// hard-coded aspect ratio feature into the Image primitive.
