nit: everything in content/public is in the content namespace. is this just
overlooked or can the objective c code not be in a namespace?

Namespaces are a C++ feature. :( That's one area where C++ and ObjC don't mix
well.

 @protocol RenderWidgetHostViewMacDelegate
 @optional
 // Notification that the view is gone.
 - (void)viewGone:(NSView*)view;
 
 // Handle an event. All incoming key and mouse events flow through this delegate
 // method if implemented. Return YES if the event is fully handled, or NO if
 // normal processing should take place.
 - (BOOL)handleEvent:(NSEvent*)event;
 
 // Notification that a wheel event was unhandled.
 - (void)gotUnhandledWheelEvent;
 
 // Notification of scroll offset pinning.
 - (void)scrollOffsetPinnedToLeft:(BOOL)left toRight:(BOOL)right;
 
 // Notification of whether the view has a horizontal scrollbar.
 - (void)setHasHorizontalScrollbar:(BOOL)has_horizontal_scrollbar;
 
 // Provides validation of user interface items. If the return value is NO, then
 // the delegate is unaware of that item and |valid| is undefined.  Otherwise,
 // |valid| contains the validity of the specified item.
 - (BOOL)validateUserInterfaceItem:(id<NSValidatedUserInterfaceItem>)item
                       isValidItem:(BOOL*)valid;
