  15 Description
  16 ===========
  17
  18 In this format each four bytes is two pixels. Each four bytes is two
  19 Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr
  20 belong to both pixels. As you can see, the Cr and Cb components have
  21 half the horizontal resolution of the Y component.
