Mitch Curtis 09dd19df5c Do not consider sign in qIsNull. ... The current implementation of qIsNull only returns true if the value is positive zero. This behaviour is not useful for use cases like QPointF::isNull, where QPointF(-0, -0).isNull() will return false. There doesn't seem to be a reason why the function exhibits this behaviour (-0.0 is not accounted for in the unit tests), and for the case of QSizeF::scale it causes a bug: qIsNull is used to check for division by 0.0 before it proceeds, which fails in the case of -0.0.
