The capture_into() function wrote out of bounds when capturing from a non-origin view (not positioned at (0,0)). At the time of implementation, this API was used to capture pixels across views into a single data buffer, but the way it's used, and the way views may work now, makes this impossible to do properly. So remove the ability to capture into a pre-allocated buffer from multiple views, and complain if the passed rectantgle overlapps with multiple views. This removes the broken offset calculation all together, fixing the bug motivating this change. https://bugzilla.gnome.org/show_bug.cgi?id=787715
