The event is not useful at all, so we are better off
with a signal that doesn't have it, and it is only
relevant on toplevel windows, so we don't need it on
GtkWidget.
With this commit, delete events no longer go through the
::event, ::delete-event, ::event-after widget signals,
but just cause the ::close-request signal on GtkWindow to be
emitted.
Using get_preferred_size here does not work since it computes the
minimum height for the minimum width, but we want to know the minimum
height for the current width.
The fix is twofold. First, when checking that a corner is resizable, we must
check the constraints on both edges. Second, when checking either edge we
must include both perpendicular sides in order to allow those to be
resizable when the constraint does not allow resizing the edge being
checked.
When looking for the cursor to apply, start from the innermost
widget and go up. This is the right behavior for cases like
entry icons. The top-down order we were using so far is the
right behavior for cases like global wait cursors. Since we
have entry icons in gtk, but not global wait cursors, lets
pick the other order for now.
application/x-rootwindow-drop is not useful anywhere else,
so put it under #ifdef GDK_WINDOWING_X11
On W32 this prevents toplevels from automatically becoming valid
drop targets with a useless drop type.

Instead of allowing people to pass a uint user-data, insist on them
comparing mime types.
The user data was a uint instead of a pointer anyway, so uniqueness
could not be guaranteed and it caused more issues than it was worth.
And that's ignoring the fact that it basically wasn't used.
Change constructors to reflect that.
While doing so, also add a fallback argument to the cursor constructors,
so it is now possible to create cursors with fallback.
The check used to achieve discarding events not meant for the window
widget itself (because they are handled in the regular paths). Using
the target widget is the equivalent now.
Use g_value_set/get_boxed() in gtk_window_get/set_property(), case PROP_ICON.
icon_from_list() shall always add a reference to the returned icon.
gtk_window_set_icon() must accept icon != NULL.

We disconnect from the GDK window, so the renderer can't keep any useful
state.
Plus, we might be using an entirely different window next time we
realize (after a call to gtk_window_set_display() for example) that should
use a completely different renderer anyway.
And have a priv->display instead of a priv->screen.
Includes turning gtk_menu_set_screen() into gtk_menu_set_display(),
because that function just forwards to its window.
