Description: Fix DND and drop indicator on desktop
(1) When items are dragged and dropped on any desktop position other than
that of a directory, they will stick to it (and to its following positions),
moving next sticky items if needed. When desktop items are dropped on
themselves or on a directory, the DND menu will be shown.
.
(2) The drop rectangle (when dragging desktop items on desktop folders) is
also fixed by drawing it explicitly.

Description: Always drop into the cell behind cursor
Drop desktop items into the cell behind the cursor, regardless of the cursor
position inside the cell.
.
Previously, if the cursor was in the right half of the cell, the item would
be dropped into the next cell on the right, and a similar thing happened with
the right bottom half.
