Increase size of one of the test files so I can use it for testing incremental builds. Needs to be large enough to leave some clean bricks.

Exclude padding when computing the range of written samples. This becomes more important once incremental build is enabled.

Keep track of statistics and histogram when a file is open for write. Not very useful yet because lowres still requires a full build.
