Bug 577878 - [GTK] Table/Tree with SWT.PaintItem don't show rows when dragging them

Rendering drag images for SWT.PaintItem case was "temporarily" disabled
for a very long time, since commit
    5a8028d0 by Steve Northover at 2008-04-29 07:56:43
    disable drag images in table and tree for custom draw

It didn't work well, because instead of using `background_area`
callback argument, it requested the value via
`gtk_tree_view_get_background_area()`, which returns screen coordinates
in Tree/Table. However, in case of rendering a drag image, an isolated
row is rendered, and coordinates are different.
