aoc10: 80x80 canvas?

[dnwe]

I was wondering how you determined from the instructions that the points would all fit within an 80x80 canvas when the message was being displayed?

advent-of-code/aoc10/src/main.rs

Lines 29 to 37 in 6285296

	for _ in 0..1_000_000 {
	points.step();
	let (w, h) = points.dimensions();
	if w <= 80 && h <= 80 {
	writeln!(io::stdout(), "seconds: {}", points.seconds)?;
	writeln!(io::stdout(), "{}", points.grid_string().trim())?;
	writeln!(io::stdout(), "{}", "~".repeat(79))?;
	}
	}
