[vtkusers] RequestData in VTK 5.8 and 5.10?

[Utkarsh Ayachit]

Thomas,

vtkMaskPoints::MaximumNumberOfPoints is being set to VTK_LARGE_ID in the
constructor of vtkMaskPoints. So its default value is indeed expected to be
large. The real issue seems to be that the code in your filter's
RequestData() where the MaximumNumberOfPoints is set to 5000 doesn't get
called. It's hard to say why it's not being called at all.
