-/*Super blocks are 32x32 segments of pixels in a single color plane indexed
- in image order.
- Internally, super blocks are broken up into four quadrants, each of which
- contains a 2x2 pattern of blocks, each of which is an 8x8 block of pixels.
- Quadrants, and the blocks within them, are indexed in a special order called
- a "Hilbert curve" within the super block.
-
- In order to differentiate between the Hilbert-curve indexing strategy and
- the regular image order indexing strategy, blocks indexed in image order
- are called "fragments".
- Fragments are indexed in image order, left to right, then bottom to top,
- from Y' plane to Cb plane to Cr plane.
-
- The co-located fragments in all image planes corresponding to the location
- of a single quadrant of a luma plane super block form a macro block.
- Thus there is only a single set of macro blocks for all planes, each of which
- contains between 6 and 12 fragments, depending on the pixel format.
- Therefore macro block information is kept in a separate set of arrays from
- super blocks to avoid unused space in the other planes.
- The lists are indexed in super block order.
- That is, the macro block corresponding to the macro block mbi in (luma plane)
- super block sbi is at index (sbi<<2|mbi).
- Thus the number of macro blocks in each dimension is always twice the number
- of super blocks, even when only an odd number fall inside the coded frame.
- These "extra" macro blocks are just an artifact of our internal data layout,
- and not part of the coded stream; they are flagged with a negative MB mode.*/
