Fixed bugs in QPainterPath::united().
Change from a relative to an absolute fuzzy compare as was the case pre-4.4. With a relative fuzzy compare points that have an x or y coordinate of 0 will never be merged with points that are very close to 0, for example (1e-15, 0). Task-number: 251909 Reviewed-by: Trond
