Subject: [PATCH] If a QWindow without a platform window is resized, emit
 changed signal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Needed as a consequence of I4f5e37480eef5d105e45ffd60362a57f13ec55f5
Otherwise a Window in QML doesn't get notified to update its layout
after being mapped the first time, on Linux.
