Summary0028230: Convert C0 2d curve to C1 raises exception
DescriptionThe method Geom2dConvert::C0BSplineToC1BSplineCurve raises exception in some cases.
The corresponding draw command is splitc12d.
It is strange that if we call it with tolerance 1e-7 it does not raise exception, and does not modify the curve. The curve remains C0.
If we call it with tolerance 1e-6 the curve becomes C1.
If we call it with tolerance 1e-5 (default for draw command) it raises exception.
The method should have consistent behavior.

This bug was the cause of the bug #28221, which was fixed by another way.
