0026841: Boolean operation "bsection" produce invalid result on the attached cases

Browse Source 
1. Intersection curve was not bounded by faces domain. It was the reason of big edge tolerance. This problem has been fixed.
2. Interface bopcurves DRAW-command has been changed in order to make possible to reproduce intersection problem.

Creation of test case for this issue.
