Fix bugs in QGraphicsItem::childrenBoundingRect()
While working on layering in Graphics View I stumbled over this bug. The
QGraphicsItem::childrenBoundingRect() function had an accumulating error
caused by recursive adding of rectangles that individually were mapped to
the local parent using QGraphicsItem::mapRectToParent() /
QTransform::mapRect. This caused the brect to be way too large for items
with children that are rotated (fex, alternating 45 and -45 degrees).
The new version should be just as fast, but with no loss of precision.
