[vtkusers] vtkPointPicker and Tcl interface,..

[Miguel Angel Rodriguez Florido]

	Resolved!!.

	It was due to the Tcl wrapper!.

	I was passing under Tcl a float value to the GetScalarComponentAsFloat 
method, and the picker was giving me a generic error like that, and not 
a clue to resolve it.

	Best.
