 * The allocator methods return a pointer to the newly allocated memory of appropriate
 * type. If device-memory allocation is not possible due to resource constaints

 * All signal allocators allocate memory aligned such that it is  beneficial to the 
 * performance of the majority of the signal-processing primitives. 
 * It is no mandatory however to use these allocators. Any valid
 * CUDA device-memory pointers can be passed to NPP primitives.
