Data Fields
int16_t *	src_diff
	Stores source - pred so the txfm can be computed later.

tran_low_t *	dqcoeff
	Dequantized coefficients.

tran_low_t *	qcoeff
	Quantized coefficients.

tran_low_t *	coeff
	Transformed coefficients.

uint16_t *	eobs
	Location of the end of qcoeff (end of block).

uint8_t *	txb_entropy_ctx
	Contexts used to code the transform coefficients.

struct buf_2d	src
	A buffer containing the source frame.

Quantizer Settings
Attention These are used/accessed only in the quantization process. RDO does not and must not depend on any of these values. All values below share the coefficient scale/shift used in TX.
const int16_t *	quant_fp_QTX
	Quantization step size used by AV1_XFORM_QUANT_FP.

const int16_t *	round_fp_QTX
	Offset used for rounding in the quantizer process by AV1_XFORM_QUANT_FP.

const int16_t *	quant_QTX
	Quantization step size used by AV1_XFORM_QUANT_B.

const int16_t *	round_QTX
	Offset used for rounding in the quantizer process by AV1_XFORM_QUANT_B.

const int16_t *	quant_shift_QTX
	Scale factor to shift coefficients toward zero. Only used by QUANT_B.

const int16_t *	zbin_QTX
	Size of the quantization bin around 0. Only Used by QUANT_B.

const int16_t *	dequant_QTX
	Dequantizer.
