[vtkusers] display tens of thousands of cubes

[Alex Southern]

Thanks again with this,

I got around to trying out vtkGlyph3DMapper, in my opinion this is the 
best way to perform this task and the interaction is much more fluid.

Although if you want to represent cubes of different sizes at the same, 
it looks like you need to make as many vtkPoint arrays, 
vtkGlyph3DMapper's and vtkActors as there are cube sizes, but this is no 
problem.

Cheers
Alex
