Comment (by gk):

 Part 1

 The needs_revision is for the following parts

 {{{
   if (w !== window.outerWidth || h !== window.outerWidth) {
 }}}
 I guess you want `h !== window.outerHeight`.

 Looking at `largestMultipleLessThan()` I was wondering why you can't just
 use `Math.floor(max / factor) * factor`? Apart from that: where did you
 find that `Math.floor()` can take two parameters?
 The function name might be misleading as the result can be equal to `max`
 as well.

 In `computeTargetZoom()` could you explain why you need `Math.min() there?
 Why not just `w - xStep` and `h- yStep` given that they are always smaller
 than `w` and `y` and thus the former function as a boundary. (The second
 `Math.min()` seems to be missing `h` as the first parameter, no?)
