0024108: Boolean fuse fails

Browse Source 
Tolerance of checking distance between vertex and edge in BOPInt_Context::ComputeVE() increased by additional Precision::Confusion() to allow for interference to be detected in this particular case.

Two tests added for this issue: one with original shapes and another in rotated co-ordinates
