-/**

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

- * The Hack physical screen consists of 512 rows of 256 pixels each.

- * The library uses a fixed font, in which each character is displayed 

- * 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

- * as a small filled square, indicates where the next character will be displayed.
