7 AFBC is a proprietary lossless image compression protocol and format.
21 AFBC streams can contain several components - where a component
22 corresponds to a color channel (i.e. R, G, B, X, A, Y, Cb, Cr).
42    * Component 0: R(8)
43    * Component 1: G(8)
44    * Component 2: B(8)
45    * Component 3: A(8)
49    * Component 0: R(8)
50    * Component 1: G(8)
51    * Component 2: B(8)
55    * Component 0: Y(8)
56    * Component 1: Cb(8, 2x1 subsampled)

65    * Component 0: R(8)
66    * Component 1: G(8)
67    * Component 2: B(8)
68    * Component 3: X(8)
70 Please note, however, that the inclusion of a "wasted" 'X' channel is
72 formats containing 'X' bits. If a fourth component is
75 '1'. If there is no requirement for a fourth component, then a format
