Removed excess mechanism for invalidating presentations AIS_InteractiveObject::myRecomputeEveryPrs.
PrsMgr_PresentableObject::Update() has been deprecated and replaced by PrsMgr_PresentableObject::UpdatePresentations()
recomputing only explicitly invalidated presentations.
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.
Some warnings were removed from MFC samples
All warnings of sample projects with warning level 4 were fixed on VC9
Warnings level increased to -W4 in projects of MFC samples; sample ReadMe files added to documentation
Changes in Viewer2dDoc.cpp and OcafDoc.cpp were restored.
Minor corrections in documentation
