There is no different code path for those big numbers, once the difference between width and the number of tracks exceeds 2 orders of magnitude then the result is 0. Anyway it won't hurt.

> -Let's cover width:0; and width:1px;

The case of width: 0px was not intentionally added because in that case the function with the ASSERT won't ever be called.
