Summary	0026250: Boolean operation should check, if faces are overlapped, before finding intersection result between these faces
Description	If faces are overlapped intersection algorithm will not been able to find correct intersection line because every point in some region is intersection point. As result, found curve can be invalid (see bug #26151). Therefore, it will be better to detect overlapping before intersection calling and to forbid calling intersection if overlapping is confirmed.
Steps To Reproduce	Test case is not required. Example of shapes can be found in bug #26151. However, fix for bug #26151 allows detecting tangencies in level of intersection algorithm
Tags	No tags attached.
