- * A library of functions for writing text on the screen.

- * within a frame which is 11 pixels high (including 1 pixel for inter-line
- * spacing) and 8 pixels wide (including 2 pixels for inter-character spacing).
- * The resulting grid accommodates 23 rows (indexed 0..22, top to bottom)
- * of 64 characters each (indexed 0..63, left to right). The top left
- * character position on the screen is indexed (0,0). A cursor, implemented
