[vtk-developers] two small fixes

[Wylie, Brian]

All,

I'm going to check in two small fixes for Clinton Stimpson 

Quote from Clinton
"The vtkPolygon::IntersectWithLine would not return a positive value if 
the line was within tolerance.  Only if it was within the boundaries of 
the polygon.  The change makes it consistent with
vtkTriangle::IntersectWithLine and others.

It was impossible to catch a cntrl-tab key in my interactor style class 
on X11.  The key char was zero (obviously) and the key sym was NULL."

Here's the patch

Let me know if there are any objections.
