/// <summary> A class which wraps a 2D array of bytes. The default usage is signed. If you want to use it as a
/// unsigned container, it's up to you to do byteValue & 0xff at each location.

/// JAVAPORT: I'm not happy about the argument ordering throughout the file, as I always like to have
/// the horizontal component first, but this is for compatibility with the C++ code. The original
/// code was a 2D array of ints, but since it only ever gets assigned -1, 0, and 1, I'm going to use
/// less memory and go with bytes.
