Fix zooming in crash...
Fix zooming in crash The bounding rect has to fit inside int limits when zooming in, meaning that the height and width both have to be within the int limits (INT_MAX). QWidget::update() uses a region (based on bounding rect) that has to be compatible with QRect. The geometry change is only done if the bounding rect fulfills this requirement.
