| A subclass of BorderExtender that implements
border extension by filling all pixels outside of the image
bounds with copies of the whole image. For example, the image:
if extended by adding two extra rows to the top and bottom and
two extra columns on the left and right sides, would become:
| E | F | D | E | F | D | E |
H | I | G | H | I | G | H |
B | C | A | B | C | A | B |
E | F | D | E | F | D | E |
H | I | G | H | I | G | H |
B | C | A | B | C | A | B |
E | F | D | E | F | D | E |
This form of extension is appropriate for data that is inherently
periodic, such as the Fourier transform of an image, or a wallpaper
pattern.
