A cell is a pair of character and attribute values. Although the Vio
subsystem supports 4-byte cells, I don't know of a display card that
actually has them instead of the standard 2-byte cells that have been
around since the ages of the CGA display card. So, here's a description of
the 2-byte format.

The first byte is the character value, 0-255. Nothing fancy about it, just
dig up an ASCII table if you want to fool around with extended characters.

The second byte is the attribute. It's a bit field:

Bits    Meaning
0-3     Foreground color
4-6     Background color
7       Blink

Color values:
=============
0 - black
1 - blue
2 - green
3 - cyan
4 - red
5 - magenta
6 - brown
7 - white
8 - dark gray
9 - light blue
10 - light green
11 - light cyan
12 - light red
13 - light magenta
14 - yellow
15 - bright white

Remember: only color values 0-7 are usable as background colors.
