I think we should also convert this to size_t if they are instantiated from
size_t (and the same in RenderFrameImpl).

Got trybot compile failure in patch set #26:

content/common/input_messages.h:150:1: error: [chromium-ipc] IPC tuple
references banned type 'size_t'

Does that mean we shouldn't use size_t here? If so, should we keep using size_t
in render_frame_impl and test_render_frame?
