A 2D canvas for rendering text, usually for console applications.

val canvas = TextCanvas(40, 8)
canvas.write(1, 20, "Such canvas")
canvas.write(6, 30, "Very 2D")
canvas.write(4, 7, "Much monospace")
println(canvas)

                                        
                    Such canvas         
                                        
                                        
       Much monospace                   
                                        
                              Very 2D   
                                        

Not very impressive. However, TextCanvas automatically handles multi-char codepoints and ANSI control sequences.

For example, rendering a red X at (0,0) and a blue O at (0, 2) means writing 10 characters each:

canvas.write(0, 0, "\u001B[31mX\u001B[0m")
canvas.write(0, 2, "\u001B[34mO\u001B[0m")

X O                                     
                    Such canvas         
                                        
                                        
       Much monospace                   
                                        
                              Very 2D   
                                        

(Note: GitHub/markdown do not allow coloring text so use your imagination)

If TextCanvas was a naive 2D char[] the O would have overwritten almost all of the X's ANSI escape sequence.
