0024800: Point of intersection was not found for 2d offset curve.

Browse Source 
For fix this case in method Geom2dInt_Geom2dCurveTool::NBSamples() number of samples for 2d offset and trimmed curve is computed as max value from number of samples for other curve and number of samples for basis curve.

Test case for issue CR24800
