Should we be using l10n_util::GetStringUTF16 for these (along with resources in
chrome/app/generated_resources.grd, as per
http://www.chromium.org/developers/design-documents/ui-localization) ?

[varunjain, 2012/03/14 18:49:08]

the talk code already has localized versions of this string. I am thinking if we
want to relocalize here or when we do the complete screen casting dialog, send
localized strings from the plugin?

I'm not familiar with the design of this area, but you can't just use English
here as I earlier noted and Josh reasserted. If you have an idea how to
reasonably handle this, go for it.
