Incorrect padding for the data source of spPostprocess2D in convolutionFFT2D.

[xduan-icx]

In "convolutionFFT2D.cu":

147 extern "C" void spPostprocess2D(void *d_Dst, void *d_Src, uint DY, uint DX,
148 uint padding, int dir) {
...
162 #if (USE_TEXTURE)
163 cudaTextureObject_t texComplex;
164 cudaResourceDesc texRes;
165 memset(&texRes, 0, sizeof(cudaResourceDesc));
166
167 texRes.resType = cudaResourceTypeLinear;
168 texRes.res.linear.devPtr = d_Src;
169 texRes.res.linear.sizeInBytes = sizeof(fComplex) * DY * (DX + padding);

Here the texture size based on "d_Src" should be "sizeof(fComplex) * DY * DX" because neither the data source passed from "test1()" in "main.cpp" nor the data access in kernel "spPostprocess2D_kernel" has padding.
