-/* Color codes: 0 = black, 1 = red, 2 = green, 3 = yellow, 4 = blue,
- * 5 = magenta, 6 = cyan, 7 = white.
- *
- * An 'attribute' as used in this library means an 8-bit value that conveys
- * a foreground color code, a background color code, and the bold
- * and blink bits. Each cell in the virtual terminal screen is associated
- * with an attribute that specifies its appearance. The bits of an attribute,
- * from most significant to least significant, are
- *
- * bit: 7 6 5 4 3 2 1 0
- * content: S F F F H B B B
- * | `-,-' | `-,-'
- * | | | |
- * | | | `----- 3-bit background color code (0 - 7)
- * | | `--------- blink bit (if on, text is blinking)
- * | `------------- 3-bit foreground color code (0 - 7)
- * `----------------- bold bit
- *
- * It is however recommended that you use the provided macros rather
- * than dealing with this format directly.
- *
- * Sometimes we will call the 'SFFF' nibble above the 'extended
- * foreground color code', and the 'HBBB' nibble the 'extended background
- * color code'. So the extended color codes are just the regular
- * color codes except that they have an additional bit (the most significant
- * bit) indicating bold/blink.
