Why not use the internal dispatcher, so the return pathways are hooked up? You
can simply not set the callback, but that'll give you a hook if you need it.

[benwells, 2012/03/29 03:29:18]

OK, that makes sense. So instead of this function there would be a function like
WebIntentsDispatcher CreateInternalWebIntentsDispatcher(WebIntentData).

After creating one of these in the browser process I'd then call
DispatchIntent(web_contents).

+// and there is no need to register a callback. Instead the intent data just
+// needs to be dispatched 'one-way' to the RenderViewHost. |intent_data| is the
+// WebIntentData to inject. |render_view_host| is the RenderViewHost to inject
+// the data into, and must not be NULL.
