/*
Images
Package image defines the Image interface:
	package image

	type Image interface {
		ColorModel() color.Model
		Bounds() Rectangle
		At(x, y int) color.Color
	}
Note: the Rectangle return value of the Bounds method is actually an image.Rectangle, as the declaration is inside
package image.

(See the documentation for all the details.)

The color.Color and color.Model types are also interfaces, but we'll ignore that by using the predefined implementations
color.RGBA and color.RGBAModel. These interfaces and types are specified by the image/color package
