      4 Summary
      5 -------
      6 Custom rendering of lines/blocks/braille characters for gapless alignment.

      8 Example
      9 -------
     10 Lines/blocks, tmux splitter, braille "graphics". The top one is with boxdraw:

     14 Description
     15 -----------
     16 Graphic lines and blocks characters such as those used by `dialog`, `tree`,
     17 `tmux` etc sometimes align with gaps - which doesn't look very nice. This can
     18 depend on font, size, scaling, and other factors.
     19 
     20 Braille is also increasingly used for graphics (`mapscii`, `vtop`, `gnuplot`,
     21 etc), and may look or align nicer when rendered as "pixels" instead of dots.
     22 
     23 This patch adds options to render most of the lines/blocks characters and/or the
     24 the braille ones without using the font so that they align perfectly regardless
     25 of font, size or other configuration values.
     26 
     27 Supported codepoints are U2500 - U259F except dashes and diagonals, and U28XX.
