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.
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.)
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.
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.
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.)
Got parameter in/out working in EditVisualization dialog. Did some
rearranging in PluginCommon interfaces and data structures. Still
doesn't do anything useful.
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?
