Some compilers don't support namespace std.  In CMake, we just define
"std" as an empty macro because it is an application, but VTK is a
library.  We cannot force the definition of such a non-vtk-prefixed macro
upon user code.  Instead, we use "vtkstd" which is either defined to "std"
or empty depending on the compiler.
