+ * The terminal layout model.
+ * 
+ * <p>
+ * This, the buffers, and the parser, comprise the core logic of the terminal emulator. This
+ * implements the Ghidra layout model, as well as the handler methods of the VT100 parser. Most of
+ * the commands it dispatches to the current buffer. A few others modify some flags, e.g., the
+ * handling of mouse events. Another swaps between buffers, etc. This layout model then maps each
+ * line to a {@link TerminalLayout}. Unlike some other layout models, this does not create a new
+ * layout whenever a line is mutated. Given the frequency with which the terminal contents change,
+ * that would generate a decent bit of garbage. The "layout" instead dynamically computes its
+ * properties from the mutable line object and paints straight from its buffers.

+ * a decent job of listing which VT version (or Tektronix, or whatever terminal) that introduced or
+ * specified each code/sequence in the last 6 or so decades, applications don't really seem to care
+ * about the details. You set {@code TERM=xterm}, and they just use whatever codes the feel like.
+ * Some make more conservative assumptions than others. For example, there is an escape sequence to
+ * insert a blank character, shifting the remaining characters in the line to the right. Despite
+ * using this, Bash (or perhaps Readline) will still re-send the remaining characters, just in case.
+ * It seems over the years, in an effort to be compatible with as many applications as possible,
+ * terminal emulators have implemented more and more escape codes, many of which were invented by
+ * XTerm, and some of which result from mis-reading documentation and/or replicating erroneous
+ * implementations.
+ * 
+ * <p>
+ * Perhaps our interpretation of the history is jaded, and as we learn more, our implementation can
+ * become more disciplined, but as it stands, our {@link TerminalPlugin} takes the <em>ad hoc</em>
+ * approach: We've implemented the sequences we need to make it compatible with the applications we
+ * intend to run, hoping that the resulting feature set will work with many others. It will likely
+ * need patching to add missing features over its lifetime. We make extensive use of the
+ * <a href="https://invisible-island.net/xterm/ctlseqs/ctlseqs.html">XTerm control sequence
+ * documentation</a>, as well as the
+ * <a href="https://en.wikipedia.org/wiki/ANSI_escape_code">Wikipedia article on ANSI escape
+ * codes</a>. Where the documentation lacks specificity or otherwise seems incorrect, we experiment
+ * with a reference implementation to discern and replicate its behavior. The clearest way we know
+ * to do this is to run the {@code tty} command from the reference terminal to get its
+ * pseudo-terminal (pty) file name. Then, we use Python from a separate terminal to write test
+ * sequences to it and/or read sequences from it. We use the {@code sleep} command to prevent Bash
+ * from reading its own terminal. This same process is applied to test our implementation.
+ * 
+ * <p>
+ * The applications we've tested with include, without regard to version:
+ * <ul>
+ * <li>{@code bash}</li>
+ * <li>{@code less}</li>
+ * <li>{@code vim}</li>
+ * <li>{@code gdb -tui}</li>
+ * <li>{@code termmines} (from our Debugger training exercises)</li>
+ * </ul>
+ * 
+ * <p>
+ * Some known issues:
+ * <ul>
+ * <li>It seems Java does not provide all the key modifier information, esp., the meta key. Either
+ * that or Ghidra's intercepting them. Thus, we can't encode those modifiers.</li>
+ * <li>Many control sequences are not implemented. They're intentionally left to be implemented on
+ * an as-needed basis.</li>
+ * <li>We inherit many of the erroneous key encodings, e.g., for F1-F4, present in the reference
+ * implementation.</li>
+ * <li>Character sets are incomplete. The box/line drawing set is most important to us as it's used
+ * by {@code gdb -tui}. Historically, these charsets are used to encode international characters.
+ * Modern systems (and terminal emulators) support Unicode (though perhaps only UTF-8), but it's not
+ * obvious how that interacts with the legacy charset switching. It's also likely many applications,
+ * despite UTF-8 being available, will still use the legacy charset switching, esp., for box
+ * drawing. Furthermore, because it's tedious work to figure the mapping for every character in a
+ * charset, we've only cared to implement a portion of the box-drawing charset, and it's sorely
+ * incomplete.</li>
