/*
* Arm Fixed-Rate Compression (AFRC) modifiers
*
* AFRC is a proprietary fixed rate image compression protocol and format,
* designed to provide guaranteed bandwidth and memory footprint
* reductions in graphics and media use-cases.
*
* AFRC buffers consist of one or more planes, with the same components
* and meaning as an uncompressed buffer using the same pixel format.
*
* Within each plane, the pixel/luma/chroma values are grouped into
* "coding unit" blocks which are individually compressed to a
* fixed size (in bytes). All coding units within a given plane of a buffer
* store the same number of values, and have the same compressed size.
*
* The coding unit size is configurable, allowing different rates of compression.
*
* The start of each AFRC buffer plane must be aligned to an alignment granule which
* depends on the coding unit size.
*
* Coding Unit Size Plane Alignment
* ---------------- ---------------
* 16 bytes 1024 bytes
* 24 bytes 512 bytes
* 32 bytes 2048 bytes
*
* Coding units are grouped into paging tiles. AFRC buffer dimensions must be aligned
* to a multiple of the paging tile dimensions.
* The dimensions of each paging tile depend on whether the buffer is optimised for
* scanline (SCAN layout) or rotated (ROT layout) access.
*
* Layout Paging Tile Width Paging Tile Height
* ------ ----------------- ------------------
* SCAN 16 coding units 4 coding units
* ROT 8 coding units 8 coding units
*
* The dimensions of each coding unit depend on the number of components
* in the compressed plane and whether the buffer is optimised for
* scanline (SCAN layout) or rotated (ROT layout) access.
*
* Number of Components in Plane Layout Coding Unit Width Coding Unit Height
* ----------------------------- --------- ----------------- ------------------
* 1 SCAN 16 samples 4 samples
* Example: 16x4 luma samples in a 'Y' plane
* 16x4 chroma 'V' values, in the 'V' plane of a fully-planar YUV buffer
* ----------------------------- --------- ----------------- ------------------
* 1 ROT 8 samples 8 samples
* Example: 8x8 luma samples in a 'Y' plane
* 8x8 chroma 'V' values, in the 'V' plane of a fully-planar YUV buffer
* ----------------------------- --------- ----------------- ------------------
* 2 DONT CARE 8 samples 4 samples
* Example: 8x4 chroma pairs in the 'UV' plane of a semi-planar YUV buffer
* ----------------------------- --------- ----------------- ------------------
* 3 DONT CARE 4 samples 4 samples
* Example: 4x4 pixels in an RGB buffer without alpha
