heh, you have a bug for it already. hooray!

Well, this is actually the meta bug for unraveling the porting layer. I'm adding
it to a lot of places and have to make sure I address them all.

optional nit: I'm not sure it's part of the style guide, but how about putting
all the inline getters together near the top? Or maybe just move the HasShelf /
GetShelf stuff down near GetShelfLayoutManager?

[sky, 2017/01/11 18:57:42]

I tried to keep related things grouped together. So workspace_controller() is
workspace related and right next to GetWorkspaceWindowState(). Similarly below
all the wallpaper related functions are grouped together.
