WebSelectionBound.h is defined in public/web.  You've introduce a dependency
from public/platform to public/web, which isn't permitted.  If you'd have
included the header rather than used a forward declaration, you would have
gotten a DEPS error.

If you want to use this type for WebLayerTreeView, you'll need to move
WebSelectionBound.h into public/platform
