0025124: [Feature request] Removal of continuity checks for offset geometries
Sometimes curve or surface, which is defined as C0, has continuity G1 or above. Offset can be built from these shapes.
Therefore, this extended checking was added into SetBasisCurve and SetBasisSurface methods.
Main changes in function BRepOffset_Tool::ExtentFace(...):
* "return" is added if intersection (in 2D-space) between two edges in a face cannot be found.
Basis curve/surface continuity value found (if G1-checking is OK) is set up as BasisContinuity (see myBasisCurveContinuity and myBasisSurfContinuity members which is returned by GetBasisCurveContinuity and GetBasisSurfContinuity() methods). This fact is used in Geom2dAdaptor and in GeomAdaptor classes.
Possibility is entered, which allows for basis elements of offset curve/surface to avoid of C0-checking.
Test cases were changed according to their new behavior.

0025477: Boolean Operations with additional tolerance - Fuzzy Boolean operations
Implementation of Fuzzy Boolean operations. Such operations allow to perform Boolean operations on the shapes
with near-coincidence between the entities of these shapes, i.e. between shapes in which some entities from one shape
are intended to be coincide with some entities from the other, but the coincidence is not precise.
API for Boolean operations has been improved to have a possibility to add new options.
Modified entities:
1. New option of setting additional tolerance have been added to the following classes:
class BOPAlgo_ArgumentAnalyzer
class BOPAlgo_BOP
class BOPAlgo_Builder
class BOPAlgo_MakerVolume
class BOPAlgo_PaveFiller
class BOPDS_DS
class BRepAlgoAPI_BooleanOperation
class BRepAlgoAPI_Check
class BRepAlgoAPI_Common
class BRepAlgoAPI_Cut
class BRepAlgoAPI_Fuse
class BRepAlgoAPI_Section
2. Following draw commands have been modified to support new functionality:
BOP commands:
bop b1 b2 [tol]
bcommon r b1 b2 [tol]
bcut r b1 b2 [tol]
bfuse r b1 b2 [tol]
bsection r s1 s2 [-n2d/-n2d1/-n2d2] [-na] [tol]
