But than we would be not have the same behaviour, if qreal is float or double. Actually I changed every code in the qml designer explicitly to double or float. It would be really nice, if the Qt classes would be has a float and a double implementation. From my perspective qreal is breaking the cross plattform promise!

That's a major source- and behaviour-incompatible change, done after the beta, with no mention in the changelog or discussion on this mailing list (unless it's an old discussion and it's only now made it through). Note that half of the issues we've found so far are due to test failures after the change in precision. That means we're introducing subtle and hard-to-find behaviour incompatibilities. I propose we revert it.
