Pads vectors with alignment > 1 with trailing zeros if the internal size is larger than the visible size.

Resizes the allocated memory for the vector. Pads the memory to be a multiple of 'AlignmentV'.
| new_size | The new size of the vector |

Resizes the allocated memory for the vector. Convenience function for setting an OpenCL context in case reallocation is needed.
| new_size | The new size of the vector |
| ctx | The context within which the new memory should be allocated |
