IntPatch/IntPatch_WLineTool.cxx - adding control of maximal ratio of distances between 3 sequential points.
tests/bugs/modalg_7/bug32569 - new test case added
tests/lowalgos/intss/bug29972_1 test case is modified according new behavior of intersection algorithm
1. New testgrid "lowalgos/intss" has been created. It will contain all test cases on geometrical intersection of two surfaces ("intersect" DRAW-command) and two faces ("bopcurves" DRAW-command).
2. New test case for the issue #28493 has been created because the problem is not reproduced on MASTER.
3. Test case (lowalgos/intss/bug24472) for the issue #29501 has been modified in order to check loops of the resulting intersection curves.
