It's useful to have an example of an extension script that handles
multiple types of things. It's also good to show that scripts can
handle data types other than strings, and can chase an address to
format data items elsewhere in the code.
This required updating the tutorial binary, adding the new script,
and updating the tutorial text and associated screen shots.
Defined a simple monochrome bitmap format, and created some pieces
for a Tic-Tac-Toe game. Wrote a tutorial that explains how to
visualize them.
Also, updated some comments.
Copied the extension script tutorial files out of the Scripts
directory and into the Tutorial directory. This makes more sense,
and makes it possible to expand the script sample without altering
the tutorial.
Reverted the Scripts sample to be an actual sample, rather than a
tutorial.
Renumbered the last two tutorials and added them to the ToC. This
gives them actual numbers rather than treating them as add-ons to
the advanced tutorial.
Moved the source files for the tutorial binaries into a subdirectory
to reduce clutter.
This does mean we have two separate copies of the inline string
sample plugins, but that's an artifact of our attempts at security.
