[vtkusers] marching squares

[Brian Alexander Todd]

Igor,

I may not understand what you are doing but, I do 2D vis with vtkRenderWindow
by texture mapping the vtkStructuredPoints dataset onto a plane (there is
an example that shows how to do this that I think is called "TPlane.tcl").
vtkTexture has a member called InterpolateOff() that I think does what
you want it to.
