**************************************************************************
* \file dtt8x8.h
* \brief DCT-II, DST-II, DCT-IV and DST-IV for Complex Lapped Transform of 16x16 (stride 8)
* in GPU
* This file contains building blocks for the 16x16 stride 8 COmplex Lapped Transform (CLT)
* implementation. DTT-IV are used for forward and inverse 2D CLT, DTT-II - to convert correlation
* results from the frequency to pixel domain. DTT-III (inverse of DTT-II) is not implemented
* here it is used to convert convolution kernels and LPF to the frequency domain - done in
* software.
*
* This file is cpompatible with both runtime and driver API, runtime is used for development
* with Nvidia Nsight, driver API when calling these kernels from Java
