From 16b92d1613e245919743be5f168abe77712ec84b Mon Sep 17 00:00:00 2001
From: Michael Drake <tlsa@netsurf-browser.org>
Date: Tue, 26 Jul 2011 13:53:42 +0000
Subject: Selection is now subordinate to html and text content types, and
 disassociated from browser windows.  Note: search currently uses
 hlcache_handle_get_content() to go from bw to h to get at c for search
 highlighting via selection.
