81cdc8713c combobox: Only react to UP/DOWN scroll events 
The old else block scrolled down for everything except GDK_SCROLL_UP
scroll events, e.g. for smooth scroll events.

40ab7e1c95 gtkmenu*: Simplify event handling 
Instead of delegating on the parent shell of a menu item/shell on a variety
of situations, Simplify event handling so:
1) Menu item selection is handled entirely on GtkMenuItem through crossing
   events.
2) The deepmost menu shell handles clicks inside and outside of it.

This avoids the rather hard to follow gtk_widget_event() calls going on all
throughout the handling of crossing and button events, and makes menus work
again.

33c5f3c193 gtkmain: Add API to get the target of a GdkEvent 
This can be used on grabbing situations to determine the target of
the event. This mainly matters for GtkMenu.

da56fae5df gtkmain: Ensure there is a current event handling crossing events 
The "current event" will be the real one that is triggering the crossing
notifications, not the synthesized events.

03a63204c1 gtkmain: Ignore GDK_CROSSING_GRAB/UNGRAB crossing events for picking purposes 
Especially with owner_events=TRUE, this doesn't mean anything for picking, as
events will be reported as usual inside the application.

65de0ebea3 gdk: Make it possible to attach user data to GdkEvents 
As event->any.window is the toplevel, this is not useful anymore to
determine the window/widget that is the target for this event. Add
helper functions to attach user data to GdkEvents so the target
widget can be stored on the gtk/ side.

These calls should be made private with the rest of GdkEvent related
API.

5483b9db2d gtkmain: Avoid doubly propagation of enter/leave events from windowing 
Crossing events are already generated when picking the new pointer position,
so we don't have to propagate the windowing crossing event as-is.

f9924b7e3e gtknotebook: Drop drag_window 
It is not necessary anymore to implement tab DnD, since we just render
it on top.

2c7102b557 gtkiconview: Remove view GdkWindow 
It's not necessary anymore for clipping nor receiving events. So just
remove it. The event handling code was expecting events in bin_window
coordinates, and have been updated to relying on widget-relative coords.

remove them.

It can be entirely replaced by a clip allocation on the widget.

e2c38ddc22 gtkwidget: Add private set_pass_through() call 
We could eventually support pointer-event in CSS here, in the mean
time add this call to replace the GdkWindow API.

ea4ee876ec gtkstack: Remove view window 
This widget already sets a clip area, so the view window can be safely
removed.

e342f90a99 gtktoolpalette: Remove child window 
This is not necessary for rendering anymore, as the clip is set by the
parent scrolledwindow. It's not necessary either for receiving input
events.

57d7c34d03 gtkflowbox: Remove child window 
This widget correctly sets up a clip, so it is not necessary neither
for rendering nor for receiving input events.

1858f310aa gtkwindow: Implement window resizing sans-GdkWindow 
We can just replace window comparisons with coordinate matching, the
cursor corresponding to edges is now set in a capture-phase motion
handler, as cursors aren't set on GdkWindows anymore.

to receive events.

072a13d0b7 gtkswitch: Remove event window 
It's not necessary anymore to receive input events. The pan gesture has
been set on the capture phase as the child widgets may capture during
bubbling.

events.

95bf1379c0 gtkwindow: Ignore implicit grabs going away if there is no focus 
There should be no circumstances where an implicit grab is requested but
no focus exists, there's however circumstances (like windowing grabs taking
input to a different window) where we might get implicit grabs being undone
when then new window didn't create a focus for the pointer itself.

b7fee9f9d2 gtkwindow: Revoke implicit grabs when activating an explicit one 
Only if they fall outside the grab widget, in that case the widget holding
the implicit grab won't be receiving events anymore, so we can just undo
it.

eaa17b2548 gtkbutton: Make windowless 
It is no longer necessary to receive events, so it's relatively straightforward
now to drop.

a72404dd5a gtk: Mass delete all GtkWidget event mask API 
We now rely on toplevels receiving and forwarding all the events
the windowing should be able to handle. Event masks are no longer a
way to determine whether an event is deliverable ot a widget.

Events will always be delivered in the three captured/target/bubbled
phases, widgets can now just attach GtkEventControllers and let those
handle the events.

ef4f0e5336 gtkwidget: Make gtk_widget_event() Accept pointing events in root coordinates 
This function will, at the last minute, ensure the event contains the right
widget-relative coordinates for the widget the event is being emitted to.

02932bc406 gtkgesture: Drop GdkWindow checks 
Those are now needless and wrong, as we get guarantees that handled
events will contain widget-relative coordinates. A side effect is
that these events are very possibly not explicitly sent to the
GdkWindow that implementations expect, any extra checks performed
through gtk_gesture_set_window() will be wrong, so the function has
been dropped entirely.

the input only window.
