a453f9d128 0028414: Data Exchange, STEP - Face on a closed surface with single inner wire and without natural bound not correctly read
Problem: From the point of view of the STEP format (and others), it is allowed
to describe a face on a surface with natural boundaries (torus, sphere) without
specifying these boundaries. Thus, a face on a closed surface and containing
an inner wire (or several) is correctly defined and describes a face with a
cutout defined by this wire. At the same time, there is a function
(ShapeFix_Face::FixOrientation) in the ShapeHealing procedure that corrects the
orientation of the wires, and it starts before the function of adding natural
boundaries (ShapeFix_Face::FixAddNaturalBound). There are many shapes that have
incorrectly oriented wires and this procedure successfully heals them, but on a
correctly specified face with single inner wire on closed surface, we do not get
the entire surface with a cutout, but a part of the surface defined by the wire.
This fix is intended to resolve this ambiguity.

Change:
1. Added function isNeedAddNaturalBound that returns TRUE if face needs to add
 natural bounds.
2. Corrected condition in FixOrientation to ignoring faces that needs to add
 natural bounds.
3. For tests in which one wire was incorrectly oriented on a closed surface,
flag AddNaturalBound was disabled.
5. Test with cutout from torus was created: bugs step bug28414.

Result: By default, it is correct to add natural boundaries, because this case
 is correct from the point of view of the STEP format and others.

39ab2e0c4d 0029916: Regressions in Data Exchange on VC 2017
The "end" file from folder "de" has been corrected to exclude comparing the number of edges in the shapes from current result with test data.
"TODO messages generated for differences were removed.
Data exchange tests were regenerated.

0e443e130c 0028097: Test system does not recognize 'fail...' messages as errors
Test parse rules are improved to recognize messages with word 'fail' or 'failure' as errors.
Test cases are corrected accordingly (TODO or REQUIRED statements added where fail messages were not noticed previously).

f6b08ecf71 0028346: Function ProjectOnSegments of ShapeAnalysis_Curve returns only single solution leading to projection result far from optimal
Subdivision of curve parametric interval based on deflection criteria is added for curve type OtherCurve in
Extrema_GExtPC.gxx. Algorithm of subdivision is implemented in Extrema_Curve(2d)Tool.cxx

New Draw command projpcurve for projection of point on CurveOnSurface is added in SWDRAW_ShapeAnalysis.cxx
projpcurve is modified to reflect "start parameter" in usage message and Draw help.

94f71cad33 0024682: Move out B-spline cache from curves and surfaces to dedicated classes BSplCLib_Cache and BSplSLib_Cache
1. B-spline cache was moved into separated classes: BSplCLib_Cache for 2D and 3D curves and BSplSLib_Cache for surfaces.

2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.

3. Algorithms were changed to use adaptors for B-spline calculations instead of curves or surfaces.

4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)

5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.

6. Test cases were modified according to the modern behavior.

7. Changes in BOPAlgo_WireSplitter, BOPTools_AlgoTools, BRepLib_CheckCurveOnSurface and ShapeAnalysis_Wire to use adaptors instead of geometric entities

8. Allow Geom2dAdaptor and GeomAdaptor in case of offset curve to use corresponding adaptor for basis curve

Modification of test-cases according to the new behavior.

15b54261a3 0022598: Approximation of p-curve by 2D line
Check whether p-curve being projected can be approximated by straight line is made before full-scale projection, to improve performance.
If straight, pcurve is created as Line only if this will lead to the same range parameterization as 3d curve, otherwise BSpline of degree 1 is created.
Re-approximation of line pcurves by bsplines removed from ShapeFix_Edge.

Test case updating to new behavior.

Added "static" keyword to the  fixPeriodictyTroubles() function.

Update of test-cases according new behavior

c97067ad95 0023439: Integration of test grid "xigs" into the new testing system
Loop back tests for iges and step files with possibility of generation of reference data.
Clean up of test scripts (removal of obsolete code, adding comments, corrected formatting)
two fixes were done (same like bug 23722 and bug 23736)
Cancelling checking for number of warnings
rewrite some test scripts in cause of this and fix 23794
Tolerance checking was weakened.
Fix to check instability on Linux (bug 23822) was added.
TODO messages was added to tests which have different results on Windows and Mandriva2010
Ability to update this TODO in regeneration mode was added.
Add fix to bug 23852
Test groups were recomposed.
'dataexch' was renamed to 'de'.
CPU limit was decreased from 2000 sec. to 1500 sec.
