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.

179fb34661 0029435: Data Exchange - Exporting wires consisting of more than one edge results in loss of color data in IGES
Colors wasn't read correctly because of incorrect curve transfers in IGESToBRep_TopoCurve.cxx
I added new calls to SetShapeResult() at the necessary places.
Also in the IGESCAFControl_Writer.cxx I added new condition because of the possible NULL exception.

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.

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.
