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.

1da98d8628 Add a progress bar to HTML export
Generation of HTML is extremely fast, but compressing thousands
of frames for wireframe animated GIFs can take a little while.

Sharing bitmaps between threads required two changes: (1) bitmaps
need to be "frozen" after being drawn; (2) you can't use Path because
BackgroundWorker isn't a STAThread.  You can, however, use a
DrawingVisual / DrawingContext to do the rendering.  Which is really
what I should have been doing all along; I just didn't know the
approach existed until I was forced to go looking for it.

Also, we now do a "run finalizers" call before generating an animated
GIF.  Without it things explode after more than 10K GDI objects have
been allocated.

971301d5b8 Fix object timeout
Remember how object references from plugins are proxy objects that
time out if you don't access them for a while?  I didn't either.

This reshuffles the code to keep WireframeObject references rather
than IVisualizationWireframe.

8c01f383e5 Implement wireframe animation
You can view the animated wireframe with the "test" button in the
visualization editor, and export it as an animated GIF.

b68e39ab6b Progress toward wireframe animations
Handle the remaining visualization editor UI controls, except for
the "test" button.  Save/restore wireframe animations in the
project file.  Changed the preview from a 1-pixel-wide line drawn
by a path half the window size to a 2-pixel-wide line drawn by a
path the exact window size.

7e92a86ffa Progress toward wireframe animations
Moved X/Y/Z rotation out of the plugin, since it has nothing to do
with the plugin at all.  (Backface removal and perspective projection
are somewhat based on the data contents, as is the choice for
whether or not they should be options.)

Added sliders for X/Y/Z rotation.  Much more fun that way.

Renamed VisualizationAnimation to VisBitmapAnimation, as we're not
going to use it for wireframe animation.  Created a new class to
hold wireframe animation data, which is really just a reference to
the IVisualizationWireframe so we can generate an animated GIF
without having to pry open the plugin again.

Renamed the "frame-delay-msec" parameter, which should start with
an underscore to ensure it doesn't clash with plugin parameters.
If we don't find it with an underscore we check again without for
backward compatibility.
