[vtkusers] hide vertices

[David E DeMarle]

I don't think so, vtkPolydata is more about holding data than it is
for rendering.

I suggest adding a visibility array and sending the polydata through a
thresholding type filter to remove the non visible elements before
rendering.

Either that, or write a new vtkPolyDataPainter that knows about the
array and respects the flag by deciding what primitives to send to GL
and what not to.
