int[][] data =
[
[1, 0, 1, 0, 0],
[1, 0, 1, 0, 0],
[1, 0, 1, 1, 1],
[1, 0, 0, 1, 0],
[5, 1, 1, 1, 0]
];
when drawn with data[i][j], prints the transpose of "data":
[1, 1, 1, 1, 5]
[0, 0, 0, 0, 1]
[1, 1, 1, 0, 1]
[0, 0, 1, 1, 1]
[0, 0, 1, 0, 0]
So, if I flip [i][j] and print a row of "j's", it'll be correct.
It's very confusing and counter-intuitive to have to remember to
swap i and j every time I use an array.
I guess when I load data from files, the i/j are already swapped
and stay consistent, but when using an array in source code, they
have to be flipped.
