Reason for revert:
fails on chrome build on windows

Original issue's description:
> cast SK_ARRAY_COUNT to make it sign agnostic
>
> By adding a cast to SK_ARRAY_COUNT, the compiler treats the
> compile-time value as if it were a const int, and like regular
> numbers, permits it to be compared to signed and unsigned
> numbers freely.
