msv 19e7092d1b 0028553: Incorrect result of the ShapeUpgrade_ShapeDivideContinuity algorithm ...

The cause of the bug was computation of incorrect UVBounds in the method ShapeAnalysis::GetFaceUVBounds. In this patch the computation of a box for a 2D curve in the method ShapeAnalysis_Curve::FillBndBox() has been improved taking into account intervals of C2 continuity.
Also the fix makes little extension of bounds when making the new surface in ShapeUpgrade_FaceDivide::SplitSurface(), so that all p-curves were fully inside.
