If std::experimental::simd is not available, there is no vectorization available and the SIMD vector size will always be one.
Then, as every number is a multiple of SIMD vector size, the padding will always be zero.

This vector stores the vectorizable data: The inner vectors contain the coordinates data fCoords[0] is the vector for the x-coords fCoords[1] is the vector for the y-coords etc.
The vector of pointers stores the pointers to the first elements of the corresponding elements
If fWrapped is true, fCoords is empty. the data can only be accessed by using fCoordsPtr.
