I'm not sure it makes sense to rename this yet. Currently, it's always an
IOSurface -- and it's being initialized in the GPU process.

To have a different name means a number of places need to be copied that are
currently OS_MACOSX || TOUCH_UI.  Unless the touch one remains SetIOSurface (I
am against that).

For instance: gpu_messages.h, and
content/browser/gpu/gpu_process_host_ui_shim.cc:243

     gfx::PluginWindowHandle window,
     int32 width,
     int32 height,
     uint64 io_surface_identifier) {
   CHECK(BrowserThread::CurrentlyOn(BrowserThread::UI));
   plugin_container_manager_.SetSizeAndIOSurface(window,
                                                 width,
