Subject: [PATCH 215/398] editeng: add EditView::GetSelectionRectangles()

This gives sd access to the selection rectangles as well (as opposed
only to the document model positions of selections).

Change-Id: Icb903e91f9e868573403b360bbe839705ddf2916
(cherry picked from commit f7764214f2ab8aff030aaeb29efd693275822761)
