/*
* YUV planar/packed subsampled textures.
*
* In each diagram we indicate (maybe part) of the data for a 4x4 texture:
*
* +---+---+---+---+
* | 0 | 1 | 2 | 3 |
* +---+---+---+---+
* | 4 | 5 | 6 | 7 |
* +---+---+---+---+
* | 8 | 9 | A | B |
* +---+---+---+---+
* | C | D | E | F |
* +---+---+---+---+
*
*
* FOURCC decoding:
* - char 0: 'Y' = packed, 'P' = planar
* - char 1: '4' = 4:4:4, '2' = 4:2:2, '1' = 4:2:1, '0' = 4:2:0
* - char 2+3: '16' = 16-bit, '10' = 10-bit, '08' = 8-bit
*
* planar = Y is first, all together, then UV comes second.
* packed = YUV is interleaved
*
* ======================= 4:4:4 lossless packed =========================
*
* Equivalent to uncompressed formats, just YUV instead of RGB. For 8-bit:
*
* pixel: 0 1 2 3
* byte: 0 1 2 3 4 5 6 7 8 9 A B C D E F
* Y0 U0 V0 A0 Y1 U1 V1 A1 Y2 U2 V2 A2 Y3 U3 V3 A3
*
* 16-bit is similar with two bytes per sample, 10-bit for uncompressed is
* equivalent to R10G10B10A2 but with RGB=>YUV
*
* ============================ 4:2:2 packed =============================
*
* 50% horizontal subsampling packed, two Y samples for each U/V sample pair. For 8-bit:
*
* pixel: 0 | 1 2 | 3 4 | 5 6 | 7
* byte: 0 1 2 3 4 5 6 7 8 9 A B C D E F
* Y0 U0 Y1 V0 Y2 U1 Y3 V1 Y4 U2 Y5 V2 Y6 U3 Y7 V3
*
* 16-bit is similar with two bytes per sample, 10-bit is stored identically to 16-bit but in
* the most significant bits:
*
* bit: FEDCBA9876543210
* 16-bit: XXXXXXXXXXXXXXXX
* 10-bit: XXXXXXXXXX000000
*
* Since the data is unorm this just spaces out valid values.
*
* ============================ 4:2:0 planar =============================
*
* 50% horizontal and vertical subsampled planar, four Y samples for each U/V sample pair.
* For 8-bit:
*
*
* pixel: 0 1 2 3 4 5 6 7
* byte: 0 1 2 3 4 5 6 7
* Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7
*
* pixel: 8 9 A B C D E F
* byte: 8 9 A B C D E F
* Y8 Y9 Ya Yb Yc Yd Ye Yf
*
* ... all of the rest of Y luma ...
*
* pixel: T&4 | 1&5 2&6 | 3&7
* byte: 0 1 2 3 4 5 6 7
* U0 V0 U1 V1 U2 V2 U3 V3
*
* pixel: 8&C | 9&D A&E | B&F
