[James Cook, 2016/07/27 20:53:17]

Are these resources used anywhere else? I only see references here and in some
generated code. If they are not used, we should delete the resources too.

[bruthig, 2016/07/27 21:08:13]

They all appear to be used by ui/views/controls/slider.cc except for
IDR_SLIDER_ACTIVE_RIGHT.

Removed IDR_SLIDER_ACTIVE_RIGHT and associated png.
