Add support for "scrolling while DND" on DND protocol
Submitted by Nelson Benitez
Assigned to Wayland bug list
Hi, I take the chance that Wayland DND protocol is in its early stages to bring attention to a cool feature that was recently added to XDND spec but never got to be implemented in GTK+, that is, to being able to scroll the target while DND by using mousewheel.
Basically we need support for the source widget to receive scroll events and transmit them to the target widget so the destination widget can scroll accordingly.
Some example usescase to get an idea:
- Drag some text in gedit and then go to nautilus and scroll to reach some folder where to drop it.
- Drag some file in a nautilus pane/window and go to another pane/window and scroll to reach a folder where to drop it.
 XDND spec added support for scrolling target in June 17, 2009 see http://www.newplanetsoftware.com/xdnd/#ChangeLog
