A new flag Prs3d_Drawer::FaceBoundaryUpperContinuity() has been introduced handled by StdPrs_ShadedShape::FillFaceBoundaries() method to exclude edges of higher continuity class (e.g. to skip seam edges). Draw Harness command vshowfaceboundary has been replaced by vaspects: > vaspects -setFaceBoundaryDraw 1 -setFaceBoundaryColor RED -setFaceBoundaryType DASH.
