Subject: [PATCH 166/398] lokdocview: Reset view completely

Resetting tiles only is not enough. We need to empty stale
selection rectangles, handle bars, cursor positions etc., so that
they do not interfere with next view to be opened using same
widget instance.

We are not destroying the document here, so the widget would
still point to the same document unless it is made to point to
another document by subsequent lok_doc_view_open_document calls.
