qmlscene can start with either an Item or Window as the qml root
Before, it assumed that the root is an Item and needs to have a Window created. But it's useful for an application to have a Window as the root, and it was already possible by writing a different C++ main function (see qtdeclarative/examples/window/window/window.cpp). It doesn't take much to give qmlscene this flexibility too. Change-Id: Ie808e78a42074e13aa9d3c87723ec9ac8fdbaf4a Reviewed-by: Samuel Rødal <samuel.rodal@digia.com>
