[vtkusers] Logo as Poly Data

[Mark Young]

I've got a black and white logo represented as a bitmap. I want to convert
the black part of the logo to PolyData so I can perform visual effects on
it.

I'm currently using vtkGeometryFilter to convert the ImageData to PolyData
but it converts all the background pixels (white) as well. Any suggestions
on how to remove them?
