Jan Arve Sæther 8c6c4df3e8 Maintain at least 500ms timestamp distance between each test function
If we had one test function that just did

tst_Mouse::f1()
{
    QTest::mouseMove(w, QPoint(0,0));
}

and another test function that did

tst_Mouse::f2()
{
    QTest::mouseMove(w, QPoint(500,500));
}

their corresponding event timestamps were only 1 apart from each other.
This meant that any code that tried to estimate the velocity of a mouse
cursor would get a really high velocity estimate inside f2(). This would
come as a surprise to most people. So to avoid this, we add a 500 ms
timestamp delay between each test function call.

In theory this could also prevent generating a mouseDoubleClickEvent
when a pair of test functions containing a press-release sequence was
run, but there is a separate pre-existing mechanism to handle that case.
