Mike Klein 89c909efee Wsign-conversion for public headers
This is an Android request for our public headers,
much like warning about unused parameters.  See bug.

In general I've made two kinds of source changes:

   1) more commonly, explicitly cast to the type which
      is being implicitly cast to at head;

   2) less commonly, flip signedness of a value we're
      storing to match how it's used more smoothly.

Much of this is self inflicted inconsistent use of size_t, unsigned,
int, int32_t, uint32_t, etc.  SkTArray is particularly tricky because
of its std::vector half-compatibility.  E.g. resize() takes size_t,
but operator[] takes int.    ¯\_(ツ)_/¯
