[vtkusers] Explicit control of pipeline execution

[Steven Boyd]

Hello,

This question echos a previous recent question by Jan Owoc.

We have developed a filter with multiple vtkImageData inputs that 
averages the input data, and we need to be able to process those inputs 
*one at a time*.

How can we explicitly control the pipeline execution within the filter? 
  Is there a way to explicity prevent all the inputs to be updated 
before the filter executes?

We'd like to update one input, process the input data, then delete the 
input from memory, and finally start to work on the next input.

Sincerely,

Steve
