|Subject: [PATCH] boxdraw: custom-draw U+25XX lines/blocks to align seamlessly
|
|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 an option to custom-draw (without using the font)
|most of the lines/blocks codepoints such that they're rendered
|identically (per size) and align perfectly regardless of font, size
|or chscale/cwscale configuration values.
|
|138 shapes are supported (U+2500 - U+259F except dashes, diagonals
|and shades), composited as 16-bit values at boxdraw_data.h .
|
|See links and references at boxdraw_data.h
