fa7816d99c dnd: When setting a dnd icon widget, unset old one 
Setting a DND icon twice should actually work and not cause warnings the
2nd time.

4b7c8218fb Use standard cursor names for DND 
At least as far as we have them. CSS has on equivalent of dnd-ask,
so we keep using that name as-is.

158dbbc88f Use CSS syntax for drop highlighting 
I hadn't noticed the :drop() pseudo state in the CSS4 Selectors
spec when I added this a while ago. This commit renames
GTK_STATE_FLAG_DND to GTK_STATE_FLAG_DROP_ACTIVE and adds
:drop(active) as equivalent to the :dnd pseudo state.

95f648147d dnd: Stop doing cancel animation in GTK+ 
Under Wayland, the compositor does it, so there is no need
for us to move the window ourselves. For X11, we are now
doing the animation from the X11 backend. Trigger that by
calling gdk_drag_drop_done().

What changes here is that we have to keep the icon_window
alive for as long as the drag context exists. Use a weak
reference to do so.

5bb12474d9 dnd: Fix issues with drag icons under Wayland 
The Wayland dnd surface must remain in place until the drag
is over. Setting it directly as the hardcoded window of the
widget we construct carries the danger that it might get
destroyed prematurely, e.g. when the application calls
gtk_drag_set_icon_name more than once and we recreate the
widget.

Instead, create a dedicated toplevel, and reparent the widget
into it. To keep the code simple, we use the same approach
under X11 as well, and make it the responsibility of the
GDK dnd code to keep the window position updated. We already
pass the current pointer position to gdk_drag_motion, which
makes this very easy.

As a side-effect of these changes, it is now possible to use
non-toplevel widgets as drag icons.

4a42aa5229 imagedefinition: Remove icon-size 
The size of icons is a property that is relevant to who is rendering the
icon, not to the icon itself.

Example: Starting a DND operation from an entry icon should cause the
icon to resize (from the entr icon's size to the DND icon size).

3f8982a0cd gtkdnd: Traverse across insensitive widgets 
The current widget lookup code bails out on insensitive widgets, there's
however legit cases where we want DnD handled by a parent of the insensitive
widget, so just keep going upwards in that case.

We also use now the widget state flags, because get_sensitive() doesn't
propagate across hierarchies, so we could conceivably find a drop site
inside an insensitive widget.

a6cafa1edb gtkdnd: Set the icon helper from the drag site onto the context 
If the icon happened to come from the drag site icon helper (ie. set through
gtk_drag_source_set_icon*), it would be referenced on the GtkDragInfo,
but not hooked into its context. This results on non visible drag windows,
until set_icon_helper() happened to be called on some path.
