+ * 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.
