ce2fbe44bb Allow browsing the whole filesystem, but expand to the current directory 
This relies on some API internals: tree._get_label_region and node._line

b5e0ec8438 Confirm overwriting files 
A Textual layout bug is unfortunately making the Yes button HUGE,
and the No button INVISIBLE, until you mouse over the dialog, which is
pretty funny...
"<file> already exists. Do you want to replace it? [Yes]"

44fe270463 Note some alternate selection tool icons using Braille 
These are pretty good candidates, paired together.
For the Free-Form Select icon (⢼⠮), I'm specifically imitating the
asymmetrical star shape from MS Paint.

3652b2bd8e Add flood fill support 
* Implemented the Fill With Color tool using the algorithm described as
  "combined-scan-and-fill span filler" on Wikipedia.
* I added handling for the affected region being None, which turned
out more complicated than I would like...
  Some cases may be able to be simplified or removed.
* Also, I moved event.stop() to the top so I don't need to call it in
multiple places when there are multiple return points.

3dbbbc1c5f Refactor away assumption that tools will affect the document at the cursor 
You could imagine having a brush with momentum, that swings around the
mouse without always reaching it. But it's just generally clearer to
not have an inadequate initial region that's then extended.

ad111e5d6c Refactor: extract tool handling from Canvas 
I wanted to avoid duplicating tool-related state between PaintApp and
Canvas, and prepare for adding different tools with more state and which
will want to live in a separate file.

This makes it slower, when running with `textual run --dev paint.py`;
when running with `python3 paint.py`, it's fine.
When running in dev mode with `textual console` devtool connected, it's
extremely much slower. But if it was faster, you'd have more messages
to scroll through, ha. So it's a tradeoff.*
*Ideally you want it to be fast and for the logs to be compacted.

In the future, I could bypass the message system for performance, but
for now I think it's better to stay idiomatic.
