Draws the player's positions for the previous and next X frames, and displays useful position information at the top of the screen.
Change line 21 to alter the text colour.
Change line 22 to alter Player 1's line colour.
Change line 23 to alter Player 2's line colour.
Change line 25 to adjust how many look behind / look ahead frames to draw player positions for.
(Fixes an issue with the previous script where I had mostly removed a piece of information that was unnecessary.)
