/*
Demonstration of "standard" mode, which is 32 x 24
characters. Each cell can have its own background and
foreground color, determined by the character in its
place. The color table contains 32 bytes, each byte
controlling the colors of a range of 8 characters.
For example, the first byte determines colors for
characters 0-7, the second byte for 8-15, etc.
