f5d97912b6 Design transparent/opaque options UI ANSI art
This is a first draft (or first 13 versions) of an ANSI art rendition of
MS Paint's transparent/opaque option selector used for the Select and
Text tools.

A somewhat silly smattering of notes:

- Emoji representation: 🛢️🔴🧊 or 🛢️🔴🟩
- More symbols considered (and some used):
  ⛀⛁⛃🛢️⬬
  ▰𝄰ᐟ⸍⸝🧊
  ╭╮🔴⏺◖◗
  ╰╯
- The red circle seems really unreliable so I don't think I can use it.
- Overlapping the red circle/sphere object is hard to represent!
- I managed to get something fairly legible in Ubuntu's terminal,
  not so much in VS Code. VS Code is harder; I might've modified some
  settings, I don't know, but it doesn't handle semigraphics as well,
  at least not on my computer. But...
- At least if you've used MS Paint before, you can recognize the general
  color/shape profile of the icons, if not parse out what the icons are
  meant to represent if you'd never looked closely at them before.
- I'm not sure if v12 or v13 is better. I moved the right border to the
  right a bit by making it Braille, but should the corners extend
  further right then (with two dots), or mirror the left border by using
  a single dot Braille character?

7bc86bc483 Fix error handling for decode_based_on_file_extension
- UnicodeDecodeError was caught in a more general error handler;
  now it's allowed to reach the more specific handler.
- UnidentifiedImageError and FormatReadNotSupported were missing return;
  now it's not caught there so it doesn't need to, as the exception will
  interrupt the control flow.

9653bfd9d8 Handle file extensions vs PIL format IDs
They usually correspond very closely, like .png -> PNG, but are
are more distinct for some formats, like .jp2 -> JPEG2000.

- Handle formats like JPEG2000 that differ in name from the extension.
- Bring my own file ext handling in line with PIL: use dotted lowercase.
- Raise an exception when a file format is detected but not supporting
  for reading or for writing, depending on the attempted operation.

26e077bce3 Unify docstring formatting according to PEP 257
I used this regexp to search for multi-line docstrings: """.*(?<!""")\n

Here's a regexp to search for class docstrings: class .*\n\s*"""
in case that's useful later.

8e6bc9d9a4 Formalize canvas events API: don't include event object in message
This has upsides and downsides.
- It's less verbose in most cases
- But event.offset I can't use unless I define that myself.
  (I wasn't even taking full advantage of this property.)
- It's clearer what's used because what is used has to be copied.
- But what's used has to be copied.

1cdf570955 Handle minimum height at end so it no longer needs one row initially
Regarding "Initial document is zero wide to avoid an extraneous character at (0,0)",
this is not necessary anymore since I (recently) changed it to set, rather than append, values.
Regarding "...but needs one row to avoid IndexError", this commit removes that constraint.
It could now be initialized with size (1, 1) or (0, 0) or even (1, 0) I suppose, although that's not really a contender.

0d2840d5da Recode samples with new efficient ANSI export
- Will this make the files smaller when compressed? Doubtful.
- Will this commit make the repo larger? Yes, since the old is kept.
- But keeping the files in line with current encoding will allow me
to see changes in encoding, using --recode-samples.
- I'm excluding files not saved with the app:
  generated files (4x4_font_template.ans and gradient_test.ans)
  which will be recreated in their original form when regenerating,
  and a manually created empty file (0x0.ans), which tests the minumum
  document size of 1x1.

d90449e2de Fix type errors in watchdog thread cleanup
- `observer` can be None, if --restart-on-changes was not passed, but
  the hotkey F2 is pressed.
- `is_alive` is a bound method, not a property. It was definitely used
  like a property in the code I referenced.

I didn't fix these type checker errors for a long time because:
  1. they never caused actual problems for me, and
  2. when adding a type annotation `observer: Observer | None`, Pyright
     gets even _more_ confused, saying it's Unknown | None instead of
     BaseObserver | None. The secret trick was to leave it unannotated.
  3. Adding parentheses to make it `is_alive()` also made Pyright seem
     even more confused, saying it was Unknown — until I added the
     conditional.
