gmf.BackgroundlayerselectorController is broken

Locally I get the following error when trying to open all three applications (mobile, desktop, desktop_alt):

AssertionError: Assertion failed: The dimensions object is required

On the online demo, I only see this error for mobile and desktop.

Introduced in #1701. I'll read about it and figure out what's missing.

You need to pass the dimensions object from the main controller to the directive.
