DESIGN: Please consider using the appropriate C++ types for this (size_t), as
per https://www.chromium.org/developers/coding-style#TOC-Types

I'm aware that you'll need to convert to int as you cross the boundary to JS,
but the safer way to do that is to keep your API preferring the safe size
(size_t) throughout, and in your bindings glue, doing the safe_numerics casts
there.

[lgarron, 2016/01/22 22:51:27]

This *particular* function is actually the wrong side of the API [1], but I've
gone ahead and pushed the cases down into `InspectorResourceAgent.cpp`.
safe_numerics isn't available there, but I asked Justin and he recommended
safeCast() as a Blink alternative.
