Fix new type conversion warning
Code cleaned to avoid MSVC compiler warnings on unused function arguments. Several useless pieces of code are removed. Changes in IntTools_EdgeFace.cxx, Blend_Walking_1.gxx, Bnd_BoundSortBox.cxx, ProjLib_ProjectedCurve.cxx are reverted (separated to specific issue for more in-depth analysis).
