Profiling tools

As for tooling, there seems to be no problem, Qt Creator integrates them already under the Analyze menu—the QML profiler, the CPU, the function profiler, and the memory analyzer. Unfortunately, this integration only works on Linux, as the tool used by Qt Creator is Valgrind, which is not available on Windows.
