1. DRAW-commands for curve/surface continuity returning were changed. 2. Output of "distmini" DRAW-command is amended. 3. Function MinMax() was moved from Standard_Real to IntPatch_ImpImpIntersection_4.gxx. 4. Incorrect computing of nbcurveC1 in Geom2dConvert::C0BSplineToC1BSplineCurve(...) function was liquidated. Test cases were changed.
