Fix use of the window geometry specification

Until now we applied the geometry in QWidget::setVisible() by
calling QWidget::move() and QWidget::resize(). But these
methods are unreliable when the window is created but not
visible yet. For example, specifying the window position by
"-geometry +0+0" will take no effect.

Apply the geometry directly to QWindow in QWindow::setVisible().
QWidget will update its geometry after the response of the window
system. Besides it allows to specify the geometry for QML
applications.
