Nice work.  BTW, I have found the work you and Bill L. have done with the VTK 
wiki examples very helpful.  Keep up the good work :-).

Yes, but I am hesitant to add a bug report without a patch.  Really busy with 
this blasted thesis at the moment.  I could file it as a reminder for a future 
'todo', but that does not seem to be in fashion.

But the double/N-component issue does not seem that hard, so I came up with a 
patch.  Please try this,

Then maybe you could add to the tests the specific case you are trying to work 
out so that we know it will not break in the future?

Thanks,
Matt
