These should be else ifs.

thanks. done.

you shouldn't be needing this function after changing the function signature,
but constants like these are defined at the top in some anonymous namespace:

e.g.
https://cs.chromium.org/chromium/src/ui/gfx/icon_util.cc?q=%22const+int%22+pa...

[ramyasharma, 2017/04/12 00:36:40]

Moved the const the anonymous namespace. Thanks.
