BRepOffset_MakeOffset.cxx - tolerance control for building planar faces is implemented,
updating tolerance for initial entities is avoided
BRepAlgo_Loop.cxx - "total" setting tolerance 0.001 is removing
BRepLib.cxx - checking of "locked" for vertex is removing in static function UpdShTol
QABugs_20.cxx - add new command OCC26441 for checking tolerance differenses between two "identical" shapes
tests/bugs/modalg_7/bug30054 - case now is "BAD", because really result shape is invalid: many faces has not closed wires with huge gaps between ends of edges. Result was "OK" only because tolerances of vertices were increased by algorithm to cover all gaps.
tests/bugs/modalg_8/bug26441 - new test case added
Other test: B3, C8, A7, C8: they were "BAD" and now are "BAD", only some problems are changed.
Multiple changes in BRepOffset_MakeOffset algorithm:
- correct fusing vertices;
- correct building intersection edges;
- correct intersecting new edges in 2D;
- correct building wire on a new face;
- correct building history.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
