PS On an image-analysis note: the generally beautiful image by Neil Marshall at:

showing a woman in a red top and gray jeans sitting on the end of a bed ... demonstrates one of the major problems with the use of cutouts, particularly for people: the light on the woman does not match the light in the scene. Her right shoulder and thigh, facing us, should be in shadow, as is the edge of the bed. She even casts a shadow towards the viewer. Also, the floor has reflectivity, and yet her shoe and leg show no reflection, only shadow.
