What's the APK size impact of adding these additional resources?

(also, what's the APK size impact of this change in general?)

[aberent, 2016/06/08 09:47:41]

At present it adds ~1.5M to the APK file size (is this a good measure?), 90% of
which is accounted for by the two new pak files (component_resources.pak and
webui_resources.pak). I will investigate what I can do to reduce this.
