GameWidget: Request pixmap in paintEvent.

Browse source 
Requesting the pixmap in `paintEvent` only loads the
pixmap when the widget first becomes visible, making loading
the library smoother. Also avoid spawning multiple singleshot
QTimers and use QObject's internal timer, with CoarseTimer precision.
