draw_test_harness.md - description of new options in Draw commands
AppDef_BSplineCompute.hxx, BRepApprox_TheComputeLineOfApprox.hxx, GeomInt_TheComputeLineOfWLApprox.hxx, Approx_BSplComputeLine.gxx - implementation of method SetPeriodic(...) and implementation periodic boundary conditions for multiline in order to get periodic multicurve.
GeomAPI_PointsToBSplineSurface.hxx, GeomAPI_PointsToBSplineSurface.cxx - adding new parameter for methods Init(...) and Interpolate(...), implementation of building periodic tangents for first and last AppDef_MultiPointConstraint of multiline for U direction of surface.
GeometryTest_APICommands.cxx - implementation of new functionality in Draw command surfapp and surfint
GeomFill_NSections.cxx
Fixing problem with bugs modalg_3 bug606_2
Wrong distance computation has been corrected.
Some test-cases have been corrected according to their new behavior. Namely, built (by approximation algorithm) curve(s) has changed its geometrical position.
1. tests/blend/simple/X4
It is not a regression because the result is not correct on both MASTER and FIX (see explanation in the issue #26740). This problem is expected to be solved after porting Fillet-algorithm to new Boolean operation. Old Boolean operations do not cover Edge-Edge tangent-zone by vertex.
2. tests/bugs/modalg_6/bug27341_318
"checknbshapes" has been deleted in order to avoid non-stable behavior (see issue #29360) of this test case. New result is OK on both Linux and Windows platform.
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
