You know how you can represent a 2D array with a 1D array by converting the coordinates to an index, right?
index = x + (y * width)

Is it possible to do the opposite? Take an index and get the corresponding (x, y) coordinates?

Because if it is, I certainly haven't been able to figure it out.

x=index % width
y=index/width
