Comment(by dustymugs):

 Actually, I've already written what I've envisioned and am currently in
 the process of writing regression tests for it and seeing how it performs
 will real data.  The algorithm I've written doesn't care if the rasters
 are aligned, just that they are of the same SRID.

 I'm not using a 3x3 kernel, rather each pass uses every third grid lines.
 So the first pass uses grid lines 0, 3, 6, 9, ..., the second 1, 4, 7,
 10,... and the third 2, 5, 8, 11...
