[ksplash] refrect windowState correctly
Review Request #125727 - Created Oct. 20, 2015 and submitted
QWindow.show() doesn't refrect its windowState property which is set by manual. As ksplashqml treats windowState(expected to be set to Qt::WindowFullScreen) we should use QWindow.setVisible(true) instead.
At present the ksplashqml view size is adjusted to the screen size by another implementation (syncResizeMode()). We might discuss about handling windowState flag. I think we expect splashscreen is displayed full-screen and handling windowState is correct approach.
applied the patch and confirmed that ksplashqml (with/without "--test") shown full-screen.
