Summary0026250: Boolean operation should check, if faces are overlapped, before finding intersection result between these faces
DescriptionIf 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 ReproduceTest 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

Dear Peter, could you analyze if it is possible to organize detection of overlapped faces just after E/F intersection?
