Subject: Add QQuickWindow synthMouseFromTouch test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Similar to the one for QQuickWidget, it tests the effect of
AA_SynthesizeMouseForUnhandledTouchEvents and verifies the
source() of the synthesized mouse event.
