33ccdd91eb Fix lastOffset calculations in Apple II hi-res visualizer
The calculations were wrong for certain situations, generating
answers that were useless or that caused a false-positive overflow
error.

This adds a couple of simple regression tests, modeled after layout
of the Lode Runner sprite sheet (which worked fine before) and the
Empire II EWS3 font (which failed).

This also bumps up some of the arbitrary limits in the visualizer.

(issue #94)

30cb96f737 Update Apple II definitions
Picked some names to fill the gaps in the language card I/O
location list.

Tweaked the hi-res sprite sheet slightly.

a2e7c88fc9 Update Apple II definitions
Added explicit widths to the 6502 vectors.

Two changes to Apple II hi-res visualization:

(1) Allow the row stride to be any value >= 1.  This is useful
when data is stored in column-major order, i.e. it's a two-byte-wide
shape, with all of the data for the first column stored before the
data for the second column.  (Set the row stride to 1, and the
column stride to the bitmap height.)

(2) Modify the layout of grids (sprite sheets and fonts), so that
we're closer to square when the item counts is low.  Otherwise the
thumbnail just looks like a dashed line.  (This one is strictly
cosmetic.)

4221602e12 Minor tweaks to wireframe viewer
Experimented with different orders of rotation for wireframe viewer.
Made perspective projection the default behavior.  Removed animation
parameters from the stored Visualization when it's not animated.

07d477fc70 Improve Apple II hi-res visualizer
Added a new category "sprite sheet", which is essentially a more
generalized version of the bitmap font renderer.  It has the full
set of options for col/row/cell stride and colors.  (Issue #74,
issue #75)

Added a flag that flips the high bits on bitmaps.  Sometimes data
is stored with the high bit clear, but the high bit is set as it's
rendered.  (Issue #76)

Also, fixed the keyboard shortcuts in the Edit Visualization Set
window, which were 'N' for both "New ___" items.  (Issue #57)

9f9e518afc Groundwork for animated Visualizations
This adds a new class and a rough GUI for the editor.  Animated
visualizations take a collection of bitmaps and display them in
sequence.  (This will eventually become an animated GIF.)

Fixed the issue where changes to tags in the set currently being
edited weren't visible to the tag uniqueness check when editing other
items in the same set.

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.)

1cdb31de32 Visualizer improvements
Various changes:
- Generally treat visualization sets like long comments and notes
  when it comes to defining data region boundaries.  (We were doing
  this for selections; now we're also doing it for format-as-word
  and in the data analyzer when scanning for strings/fill.)
- Clear the visualization cache when the address map is altered.
  This is necessary for visualizers that dereference addresses.
- Read the Apple II screen image from a series of addresses rather
  than a series of offsets.  This allows it to work when the image
  is contiguous in memory but split into chunks in the file.
- Put 1 pixel of padding around the images in the main code list,
  so they don't blend into the background.
- Remember the last visualizer used, so we can re-use it the next
  time the user selects "new".
- Move min-size hack from Loaded to ContentRendered, as it apparently
  spoils CenterOwner placement.

4696132dfa Make visualization edit window resizable
The preview window changes size to match, providing an easy way to
get a "zoomed in" view of the image.

b56bdb7743 Split operand selection set at visualizations
Also, added a colStride/rowStride test to Apple II bitmap test.
Removed ClunkyColor.  Made color conversion mode selectable for
debugging.

4bf1ab2799 Tweak visualizer interface
Report visualization generation errors through an explicit
IApplication interface, instead of pulling messages out of the
DebugLog stream.

Declare that GetVisGenDescrs() is only called when the plugin is in
the "prepared" state, so that plugins can taylor the set based on
the contents of the file.  (This could be used to set min/max on
the "offset" entries, but I want special handling for offsets, so
we might as well set it later.)

4ef1d7e7c7 Implement Apple II hi-res bitmap font and screen image visualizers
Bitmap fonts are a series of (usually) 1x8 bitmaps, which we arrange
into a grid of cells.

Screen images are useful for embedded screens, or for people who want
to display stand-alone image files as disassembly projects.

df04de61e6 Improve visualization
Various improvements:
- Switched to ReadOnlyDictionary in Visualization to make it clear
  that the parameter dictionary should not be modified.
- Added a warning to the Visualization Set editor that appears when
  there are no plugins that implement a visualizer.
- Make sure an item is selected in the set editor after edit/remove.
- Replaced the checkerboard background with one that's a little bit
  more grey, so it's more distinct from white pixel data.
- Added a new Apple II hi-res color converter whose output more
  closely matches KEGS and AppleWin RGB.
- Added VisHiRes.cs to some Apple II system definitions.
- Added some test bitmaps for Apple II hi-res to the test directory.
  (These are not part of an automated test.)

2f56c56e5c Add visualization thumbnails
Thumbnails are now visible in the main list and in the visualization
set editor.  They're generated on first need, and regenerated when
the set of plugins changes.

Added a checkerboard background for the visualization editor bitmap
preview.  (It looks all official now.)

125080dbda Finish basic visualization editor implementation
The Visualization and Visualization Set editors are now fully
functional.  You can create, edit, and rearrange sets, and they're
now stored in the project file.

365864ccdf More progress on visualization
Implemented Apple II hi-res bitmap conversion.  Supports B&W and
color.  Uses essentially the same algorithm as CiderPress.

Experimented with displaying non-text items in ListView.  I assumed
it would work, since it's the sort of thing WPF is designed to do,
but it's always wise to approach with caution.  Visualization Sets
now show a 64x64 button as a placeholder for the eventual thumbnail.

Some things were being flaky, which turned out to be because I
wasn't Prepare()ing the plugins before using them from Edit
Visualization.  To make this a deterministic failure I added an
Unprepare() call that tells the plugin that we're all done.

NOTE: this breaks all existing plugins.

9244ceda7c More progress on visualization
Added some rudimentary bitmap creation code.  Got a test pattern
generated by the plugin to display in the app.  (Most of the time
required for this was spent figuring out how bitmaps are handled
in WPF.)

e7fccfda03 More progress on visualization
Got parameter in/out working in EditVisualization dialog.  Did some
rearranging in PluginCommon interfaces and data structures.  Still
doesn't do anything useful.

836626bdc3 Work in progress on visualization
Basic infrastructure for taking a list of parameters from a plugin
and turning it into a collection of UI controls, merging in values
from a Visualization object.  Doesn't yet do anything useful.

WPF makes the hard things easy and the easy things hard.  This was
a hard thing, so it was easy to do (with some helpful sample code).
Yay WPF?
