Create a new non-modifiable buffer that represents the given POD array.
template< typename PodType, std::size_t N> const_buffers_1 buffer( const std::array< PodType, N > & data, std::size_t max_size_in_bytes);
A const_buffers_1
value equivalent to:
const_buffers_1( data.data(), min(data.size() * sizeof(PodType), max_size_in_bytes));
