[vtkusers] about vtkImagetoImageFilter?

[Naveen Kumar Polapally]

hi,

In this filter the image extent is being split recursively and being 
assigned to a thread with an upper bound on the number of threads,but how 
does it keep track of how it should piece them back.Is this stored in parent 
thread which spawns the child threads.

Same with the vtkDataStreamer,here the extent is split and is pushed into a 
stack and an upper bound is fixed on the size of Data allowed.
how does it keep track of which pieces to append.

Can some one help me in understanding these filter?
