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

Subject: [PATCH] This patch allows to add spare font besides default. Some
|
||||||
|
glyphs can be not present in default font. For this glyphs st uses
|
||||||
|
font-config and try to find them in font cache first. This patch append fonts
|
||||||
|
defined in font2 variable to the beginning of font cache. So they will be
|
||||||
|
used first for glyphs that absent in default font.
