Is there a difference between QWindowSystemInterface and
QApplication::postEvent/QApplication::notify ? Can QTestLib use them
instead of it's current use of QWSI? Maybe it's the 'spontaneousness'
which is the difference but that can be easily fixed with a public
internal function.

As for 2, I tried to do exactly that with
https://codereview.qt-project.org/#change,23440 but the idea was shot
down. I don't know how we can make a qtestlib that doesn't depend on
widgets. I think Stephen opposed it previously because a) widgets is
non-essential module and b) he wanted corelib tests to depend only on
corelib.
