1) Remove duplicating presentation algorithms for shapes StdPrs_WFShape, StdPrs_WFDeflectionShape. 2) Rewrite Prs3d_WFShape to use deflection for non-triangulated shapes and rename it to StdPrs_WFShape. 3) Revise and correct references in code. 4) Rename StdPrs_ToolShadedShape to StdPrs_ToolTriangulatedShape (reused in StdPrs_WFShape, StdPrs_ShadedShape). 5) Add StdPrs_BndBox for drawing bounding box presentation. 6) Implemented on-triangulation isoline builder. 7) Add option -isoontriangulation to vaspects command to enable on-triangulation isoline builder for shape. 8) Drawer's maximum UV parameter value is taken into account in isolines calculation correctly. 9) Add option -setMaxParamValue to vaspects command to change drawer's maximum UV parameter value.
