nit: perhaps also call ui::MaterialDesignController::Initialize()?

[James Cook, 2016/05/16 21:32:18]

ui::MaterialDesignController::Initialize() is done as part of views::AuraInit
construction on the line above. It needs to be done down in //ui for tests, but
the ash init has to happen at a higher level, like Chrome browser main (where it
is done for Chrome) or here.

Acknowledged.

     views::WindowManagerConnection::Create(connector, identity);
 
     display::Screen* screen = display::Screen::GetScreen();
