+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
