[vtkusers] TCL to C++, need HELP

[Amy Squillacote]

Hi Rio,

The line of Tcl code in question would look like the following in C++. 
You actually need a few of lines of C++ code because 
iren->GetEventPosition() returns a vector of length 2, and you need 3 
values to pass to the picker.

int pos[2];
iren->GetEventPosition(pos);
picker->Pick(pos[0], pos[1], 0, ren1);
