|Subject: [PATCH] boxdraw_v2: custom render lines/blocks/braille for perfect
| alignment
|
|It seems impossible to ensure that blocks and line drawing glyphs
|align without visible gaps for all combinations of arbitrary font,
|size and width/height scale factor.
|
|This commit adds options to render most of the lines/blocks and
|braille codepoints without using the font such that they align
|perfectly regardless of font, size or other configuration values.
|
|Supported codepoints are U+2500 - U+259F except dashes/diagonals,
|and U28XX.
|
|The lines/blocks data is stored as 16-bit values at boxdraw_data.h
|
|boxdraw/braille are independent, disabled by default at config[.def].h
