[vtkusers] Problem with VolumeMapper & StructuredPointsReader

[Hari Sundar]

Hi Amy,

It works now, but I am a bit confused. Shouldn't including
vtkStructuredPointsReader be enough ? Doesn't it include
vtkStructuredPoints ? This particular case is simple enough, but what
would be the general rule for including headers ?

thanks,
-Hari
