Nowhere. The original cage poition is not filled if its not checked. In 
photograhic images when working with clear cut objects that might sometimes be 
useful.

Nobody has asked for that, but I guess it is doable as long as gegl provides 
nearest neighbor sampler.

Ive seen this one, but Im yet to find a criteria for replicating it. Its 
alsopossible that the redactoring Mitch did last night fixed it,

That's what the empty gegl buffer is colored. I guess the expectation in this 
area was not clearly defined. I guess it will be fixed sometime.
