cb6ceafd73 Make operand wrap length configurable
Long operands, such as strings and bulk data, can span multiple lines.
SourceGen wraps them at 64 characters, which is fine for assembly
output but occasionally annoying on screen: if the operand column is
wide enough to show the entire value, the comment column is pushed
pretty far to the right.

This change makes the width configurable, as 32/48/64 characters,
with a pop-up in app settings.

The assemblers are all wired to 64 characters, though we could make
this configurable as well with an assembler-specific setting.

Some things have moved around a bit in app settings.  The Asm Config
tab now comes last.  Having it sandwiched in the middle of tabs that
altered the on-screen display didn't make much sense.  The Display
Format is now explicitly for opcodes and operands, and is split into
two columns.  The left column is managed by the "quick set" feature,
the right column is independent.

195c93a94a Reboot sandbox when required
Another chapter in the never-ending AppDomain security saga.

If a computer goes to sleep while SourceGen is running with a project
open, life gets confusing when the system wakes up.  The keep-alive
timer fires and a ping is sent to the remote AppDomain, successfully.
At the same time, the lease expires on the remote side, and the objects
are discarded (apparently without bothering to query the ILease object).
This failure mode is 100% repeatable.

Since we can't prevent sandbox objects from disappearing, we have to
detect and recover from the problem.  Fortunately we don't keep any
necessary state on the plugin side, so we can just tear the whole
thing down and recreate it.

The various methods in ScriptManager now do a "health check" before
making calls into the plugin AppDomain.  If the ping attempt fails,
the AppDomain is "rebooted" by destroying it and creating a new one,
reloading all plugins that were in there before.  The plugin binaries
*should* still be in the PluginDllCache directory since the ping failure
was due to objects being discarded, not AppDomain shutdown, and Windows
doesn't let you mess with files that hold executable code.

A new "reboot security sandbox" option has been added to the DEBUG
menu to facilitate testing.

The PluginManager's Ping() method gets called more often, but not to
the extent that performance will be affected.

This change also adds a finalizer to DisasmProject, since we're relying
on it to shut down the ScriptManager, and it's relying on callers to
invoke its cleanup function.  The finalizer throws an assertion if the
cleanup function doesn't get called.

4928dfd872 Tweak security menu items
Changed "Use Keep-Alive Hack" to "Disable Keep-Alive Hack" to emphasize
that it defaults to enabled.  Added a menu item for "Disable Security
Sandbox".  Added a warning to both that tells the user that they must
reopen the current project for the change to take effect.

Note neither of these is persisted in app settings.

The new name is more indicative of the purpose of the directory.

Updated the docs to point out that you can delete the contents any

Also, change the default column widths for the exporter.

9aaa37a23c Add Cxxx I/O locations in bank $e0 for Apple IIgs
On an Apple IIgs, the memory-mapped I/O locations are actually in
bank $e0, shadow-copied to bank $00.  This adds a copy of the
relevant definitions from Cxxx-IO.sym65, with the addresses in bank
$e0 and "_GS" appended to the labels.

This is now included by default for the Apple IIgs system defintions.

(I thought about just adding them to Cxxx-IO.sym65, but then they
pollute the namespace for 8-bit systems.  Stripping them out at run
time got a little complicated because the platform symbols are only
loaded once, and we'd have to reload them every time the CPU definition
changed.  Further, there are a few aliases provided as constants, and
constants are allowed to be 32 bits on all systems, so those can't be
stripped.  Rather than defining a new definition I figured it was
just easier to have a second file.  Maintenance shouldn't be too taxing,
as definitions for 40-year-old machines don't change all that often.)

(I also thought about trying to make the address mirroring stuff work
for me here, but that would result in accesses being made to the
canonical address with an offset of +$e00000, which looks awful.)

e82dc31da6 Move Disk ][ defs into separate platform symbol file
The Disk ][ I/O locations are generally accessed as an offset, using
something like "LDA $C08n,X".  However the range from $C080-C08F is
already used for language card in slot 0.  SourceGen doesn't have a
way to distinguish between indexed and direct accesses, and even if
it did there's no way to separate one peripheral card from another
without knowing the contents of the CPU register.

As a workaround, the Disk ][ definitions are now in a separate symbol
file.  When loaded, the definitions replace the base slot 0 equates.

I figure Disk ][ accesses are more common than language card
manipulation, so I'm making it a default for new projects.  Existing
projects that reference the Disk ][ symbols (which existed, but as
constants) will need to be updated to include the new .sym65.

cc6ebaffc5 Update relocation data handling
When we have relocation data available, the code currently skips the
process of matching an address with a label for a PEA instruction when
the instruction in question doesn't have reloc data.  This does a
great job of separating code that pushes parts of addresses from code
that pushes constants.

This change expands the behavior to exclude instructions with 16-bit
address operands that use the Data Bank Register, e.g. "LDA abs"
and "LDA abs,X".  This is particularly useful for code that accesses
structured data using the operand as the structure offset, e.g.
"LDX addr" / "LDA $0000,X"

The 20212-reloc-data test has been updated to check the behavior.

18e6951f17 Add Data Bank Register management, part 1
On the 65816, 16-bit data access instructions (e.g. LDA abs) are
expanded to 24 bits by merging in the Data Bank Register (B).  The
value of the register is difficult to determine via static analysis,
so we need a way to annotate the disassembly with the correct value.
Without this, the mapping of address to file offset will sometimes
be incorrect.

This change adds the basic data structures and "fixup" function, a
functional but incomplete editor, and source for a new test case.

8d291ba21e Fix bank for AbsInd and AbsIndLong addressing
The Absolute Indirect and Absolute Indirect Long addressing modes

d58b747571 Use relocation data to format instruction operands
This was a relatively lightweight change to confirm the usefulness
of relocation data.  The results were very positive.

The relatively superficial integration of the data into the data
analysis process causes some problems, e.g. the cross-reference table
entries show an offset because the code analyzer's computed operand
offset doesn't match the value of the label.  The feature should be
considered experimental

The feature can be enabled or disabled with a project property.  The
results were sufficiently useful and non-annoying to make the setting
enabled by default.

c47beffcee Add Export feature to visualization editor
It's nice to be able to save images from the visualization editor
for display elsewhere.  This can be done during HTML export, but
that's inconvenient when you just want one image, and doesn't allow
the output size to be specified.

This change adds an Export button to the Edit Visualization dialog.
The current bitmap, wireframe, or wireframe animation can be saved
to a GIF image.  A handful of sizes can be selected from a pop-up
menu.

bb830a29db Add Navigate > Jump to Operand
If you double-click on the opcode of an instruction whose operand is
an address or equate, the selection jumps to that address.  This
feature is now available in the Navigate menu, with the keyboard
shortcut Ctrl+J.

While testing the feature I noticed that the keyboard focus wasn't
following the selection, so if you jumped to an address and then
used the up/down arrows, you jumped back to the previous location.
(This was true when double-clicking an opcode to jump; it was just
less noticeable since the next action was likely mouse-based.)  This
has been fixed by updating the ListView item focus when we jump to a
new location.

a bit.  Giving it a try.)

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.

b3dacc2613 Switch to left-handed coordinate system
There's no "standard" coordinate system, so the choice is arbitrary.
However, an examination of the Transporter mesh in Elite revealed
that the mesh was designed for a left-handed coordinate system.  We
can compensate for that trivially in the Elite visualizer, but we
might as well match what they're doing.  (The only change required
in the code is a couple of sign changes on the Z coordinate, and an
update to the rotation matrix.)

This also downsizes Matrix44 to Matrix33, exposes the rotation mode
enum, and adds a left-handed ZYX rotation mode.

This does mean that meshes that put the front at +Z will show their
backsides initially, since we're now oriented as if we're flying
the ships rather than facing them.  I considered adding a 180-degree
Y rotation (with a tweak to the rotation matrix handedness to correct
the first rotation axis) to have them facing by default, but figured
that might be confusing since +Z is supposed to be away.

Anybody who really wants it to be the other way can trivially flip
the coordinates in their visualizer (negate xc/zc).

The Z coordinates in the visualization test project were flipped so
that the design is still facing the viewer at rotation (0,0,0).
