Using a build of Qt with the UBSAN sanitizer enabled, the attached svg file triggers undefined behaviour due to an integer overflow happening in different places in QRect and QRectF.

The first one happens in QRectF::toAlignedRect while calculating the width and height of the rect. Once this one is fixed, the same issue is detected in the QRect constructors as they are doing the similar mathematical operations that can be found in toAlignedRect.
