the fact that this requires the presence of a RVH means that pepper fullscreen
can't use this code path. Is this intended?

Currently this is only used by web pages containing pepper/NaCl or javascript
applications.

We do have a pepper example that uses fullscreen and mouse lock:
src/ppapi/examples/mouse_lock/mouse_lock.cc

yzshen initially placed the mouse lock etc code at the RenderWidget level
because the implementation is done in the platform specific RenderWidgetHostView
objects, and related IPC messages already pass through the Widget. yzshen also
intends to add additional support for non RenderViewHost instances using mouse
lock, and will add implementation when needed.
