Built-in font for box drawing

[raphamorim]

When true, Rio will use a custom built-in font for box drawing
characters (Unicode points U+2500 - U+259F), legacy computing symbols
(U+1FB00 - U+1FB3B), and powerline symbols (U+E0B0 - U+E0B3).

builtin-box-drawing = true

sextant symbols from U+1FB00 to U+1FB3B

Would it be possible to include Braille symbols into the pretty aligned rendering as well please?

There are visible gaps between lines of Braille symbols, at some font sizes more visible than others. I have tried many terminals and Wezterm is the only one that renders Braille symbols neatly aligned so that lines are not recognizable.

I'm including some images to illustrate what I mean.

@TomLebeda could you send me later if possible the art of the viking or give the instructions to reproduce locally?

Also let's move to a new issue 🙏

[TomLebeda]

@raphamorim Of course, thanks for considering this! I have created the new issue #1057 and the art is there as well.
