I take it you decided against passing a WebSecurityOrigin here.

WebSecurityOrigin doesn't exist yet.  I plan to go back and add that class
later.  There are other places in WebKit API where "security origin" is passed
as a string, so it seemed out-of-scope to create WebSecurityOrigin as part of
this CL.
