[vtkusers] Fwd: error when including vtkSelectionNode

[David E DeMarle]

As long as you don't have to use the vtkSelectionNode::EPSILON() key
directly in your own code, moving the include above your #define
should be alright I think.

Yes, it is true. Thank you. I found it, I have "#define EPSILON 0.001"

One more question. I include vtkSelectionNode before the file that
contains that epslion defining line.
There will be no problems? or I have to change the name of that
variable call EPSILON (my variable) ?

Thank you!
