This conversion should be automatic, does it not work if you just specify
url('chrome://theme/IDR_PRODUCT_LOGO_32')?

It would probably work, but for that I'd have to move oobe.html from an include
to a structure, and I don't have a CrOs build to test this change at hand. So
I'm trying to keep the diff simple here too.

[flackr, 2012/07/04 16:36:21]

Can you add a TODO for that? Thanks!

Done.
