FIX: ShapeOps::getHomogenous...() were not working.

  • replaced for_each by transform (the latter actually replaces).
  • also by using ShapeOpsBase_Impl::translateOutPos() we can implement the getHomogeneous...() functions more generally inside ShapeOpsBase_Impl instead of specifically for each Shape operation.
  • added Implementation of getHomogenousPointsOnSurface unit test function.
  • Property mode set to 100644
