【どう書く】高速・省メモリなセルのクリッピング塗り潰しアルゴリズムについて
一次元配列X上に並んだ有限個のセルを考える。
□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□ ...
これに、範囲オブジェクト(start, end)を与えると、
その範囲のセルが塗りつぶされる作用を持つ関数Fillを考える。
※ ここで、(start, end) は、start <= n < end を満たす
インデックス n でアクセス可能なセル X[n] の集合を表現している。
たとえば、範囲オブジェクト (3, 7) で表される領域には、

# SIXEL color graphics DEMO

# xterm pl#301 with --enable-sixel-graphics option
# gnuplot with --with-bitmap-terminals option

# Now the color palette of xterm VT-340 mode is limited to 16.
# If you want to change it to 256, apply the following patch.

Proposal for resolving character-cell width problems in multilingual terminal emulators.

[Draft] glyph width query / report escape sequence

This document proposes two new escape sequences based on yaft's glyph width reporting feature.

YF_RQGRW - request glyph width list

The host sends this control string to retrive terminal-specific definition for character-cell width. The terminal is expected to respond with a YF_RPGRW sequence.
