* Vector types
*
*  Note:   OpenCL requires that all types be naturally aligned.
*          This means that vector types must be naturally aligned.
*          For example, a vector of four floats must be aligned to
*          a 16 byte boundary (calculated as 4 * the natural 4-byte
*          alignment of the float).  The alignment qualifiers here
*          will only function properly if your compiler supports them
*          and if you don't actively work to defeat them.  For example,
*          in order for a cl_float4 to be 16 byte aligned in a struct,
*          the start of the struct must itself be 16-byte aligned.
*
*          Maintaining proper alignment is the user's responsibility.
