would return the red component of the pixel from picture 3 |

that is left 2 and up 1 from the current position. |

Although x offsets may be as large as width of the picture, |

y offsets are limited to a small window (+/- 8 pixels) due to efficiency |

However, it is not usually necessary to worry about this problem -- |

if the requested offset is not available, the next best pixel is |

can grow disproportionately after multiple runs of |
