#* the current downsampler does not pad empty data when a brick is not of a regular size. Nancy and I implemented in this way because it was easier than padding. However, this causes lots of problems from the reader part, mostly additional checking codelet whether a brick has a regular size, e.g. 128, or smaller than that. Due to the exception, we need couple more variables for boundary bricks of which size is usually smaller than the brick size. By padding, these inefficient and unnecessary data can be removed.
