e622afd929 Tweak DVG visualizer
Adopted the naming conventions from the "Hitch-Hacker's Guide" doc.
Updated some comments.  No change in behavior.

d48ab7582f Add Atari DVG visualizer
The DVG format, used for vector games like Asteroids, is the
predecessor to the AVG graphics used in games like Battlezone.

Also, added some extended error checks on wireframe vertices.

Also, minor edits to the README and daily tips.

6d582c80d3 Add simple SGEC reader
SourceGen Edit Commands is a feature that allows you to generate
commands into a file and have SourceGen apply them to the current
project.  I'm not expecting this to be used by anyone but me, so
for now I'm just adding an entry to the debug menu that can read
comments out of a file.

Also, fixed a bug in the re-centering min/max code that prevented
it from working on trivial shapes.

Also, renamed the atari-avg visualizer to atari-avg-bz, with the
expectation that one day somebody might want to create a variant
for newer games.

356492d6da Add Atari AVG visualizer
This converts AVG commands to wireframes.  We don't try to track
color or intensity.  (This is a disassembler, not a graphics
converter; perfection is not required.)  The various rotation and
animation options are still enabled, though they're not terribly
useful for this.

Commands that are meant to be used in series, such as font glyphs,
tend to use (0,0) as their left edge and baseline.  This puts the
shape in the upper-right corner of the thumbnail, which makes
everything smaller.  The change adds a "re-center" option to the
wireframe renderer that computes the visible bounds and adjusts
the coordinates so that the center of the object is at (0,0) for
display.

676ab2554d Fix Atari 2600 sprite visualizer
Should be solid/transparent not white/black.  Added a blue color
to the palette to use for sprites, as white + transparent disappears
completely on web pages with a white background.

Black + white + grey seems fine for playfields.

e82678126f Various minor tweaks
Added comments, renamed files, removed cruft.

Stop showing the visualization tag name in the code list.  It's
often redundant with the code label, and it's distracting.  (We may
want to make this an option so you can Ctrl+F to find a tag.)

3c541089a7 Tweak Atari 2600 visualizer
Changed "row duplication" to a straight "row thickness".  Feels more
intuitive.

5635a1e33a Add Atari 2600 sprite/playfield visualizer
First swing at a visualizer for Atari 2600 sprites and playfields.
Won't necessarily present an accurate view of what is displayed on
screen, but should provide a reasonable shape for data stored in
the obvious way.

The Adventure playfields looked squashed, so I added a simple row
duplication value.

Also, minor improvements to visualizers generally:
- Throw an exception, rather than an Assert, in VisBitmap8 when the
  arguments are bad.
- Show the exception in the Visualization Edit dialog.
- If generation fails and we don't have an error message, show a
  generic "stuff be broke" string.
- Set focus on OK button in Visualization Set Edit after editing,
  so you can hit Enter twice after renaming a tag.

4d8ee3fd07 External symbol I/O direction and address mask, part 2
First cut at lookup-by-address implementation.  Seems to work, but
needs full tests.

9c3422623d External symbol I/O direction and address mask, part 1
Memory-mapped I/O locations can have different behavior when read
vs. written.  This is part 1 of a change to allow two different
symbols to represent the same address, based on I/O direction.

This also adds a set of address masks for systems like the Atari
2600 that map hardware addresses to multiple locations.

This change updates the data structures, .sym65 file reader,
project serialization, and DefSymbol editor.
