I falsely assumed KDevHash was being used for non-integral types, too (bad grep through source code).</p></pre>

we leverage qHash and boost::hash_combine to create an overall
hash. The result should be just as good, as it's proven technology,
but the hash functions themselves become much faster. This is
demonstrated by the newly added benchmark.</p>
