Pixel Art Algorithm: Pixel Perfect

Filter out and don't dab a pixel if it would result in creating a degenerate section of pixel art.

pub fn pixel_perfect(path: &[Pixel]) -> Vec {
    if path.len() == 1 || path.len() == 0 {
        return path.iter().cloned().collect();
    }
    let mut ret = Vec::new();
    let mut c = 0;

    while c < path.len() {
      if c > 0 && c+1 < path.len()
        && (path[c-1].point.x == path[c].point.x || path[c-1].point.y == path[c].point.y)
        && (path[c+1].point.x == path[c].point.x || path[c+1].point.y == path[c].point.y)
        && path[c-1].point.x != path[c+1].point.x
        && path[c-1].point.y != path[c+1].point.y
      {
        c += 1;
      }

      ret.push(path[c]);

      c += 1;
    }

    ret
