Implement DnD drag window
Last modified: 2016-01-18 23:53:26 UTC
On the wl_data_device implementation there seems to be just minimal code to handle the surface set during a DnD operation. This surface should probably be exposed as an actor, so it is shown following the pointer, and snapback/fade animations can be applied when DnD fails.
I started working on this in a local branch. Pushed to https://git.gnome.org/browse/mutter/log/?h=wip/dnd-surface Right now it doesn't compile, but you can sort of see the approach I was going for.
This was implemented some time ago...
