- Center the canvas (when it's smaller than the viewport).
- Adjust the scroll position when entering View Bitmap mode to anchor
the top/left (when the image is larger than the viewport).
- Restore the scroll position when exiting View Bitmap mode.
Avoid the cell background showing past the left/top of the border of the cell, by using left/top-aligned characters (▛▌▀) rather than centered border characters (┼┆┄).
I was hoping this would fix the Python rocket icon showing in the dock on macOS, but it doesn't. It still stays until the program exits.
Might still be good to do though.

While Pyright can narrow down the type of format_id from `str | None` to `str` based on `format_id in Image.SAVE` (where `Image.SAVE` is `dict[str, Any]`), mypy does not.
