We create various windows during the initial creation of display
objects, which causes some bootstrapping issues when we try to
find the default screen to get its root window. To work around this,
pass the display object into gdk_window_new.
This is not an API change, since gdk_window_new is no longer public API.
This just applied to child windows, but now GDK should just take care of
toplevels, which shall get crossing events from the windowing when the right
conditions apply.
Removing this code fixes confused crossing state in widgets and messed up
window_under_pointer tracking (Which now is meant to be toplevels) when any
of the remaining child GdkWindows trigger these crossing events.
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.
We can't really support these on e.g. wayland anyway, and we're trying
to get rid of subwindow at totally in the long term, so lets drop this.
It allows us to drop a lot of complexity.
Adds the gdk_display_ref_vulkan() and gdk_display_unref_vulkan()
functions which setup/tear down VUlkan support for the display.
Nothing is using those functions yet.
These complicate a lot of GdkWindow internals to implement features
that not a lot of apps use, and will be better achieved using gsk.
So, we just drop it all.
The update tracking code was ugly and using deprecated drawing APIs. It
was also in the wrong place.
So instead of trying to keep it working, I'll remove it. We need to find
a better way to put it and make it work there.
Instead of giving out Cairo contexts, GdkWindow should provide a
"drawing context", which can then create Cairo contexts on demand; this
allows us to future proof the API for when we're going to use a
different rendering pipeline, like OpenGL.

This allows us to decide when the R and B color channels should be
flipped with a much better granularity.
For instance, when using GLX_EXT_texture_from_pixmap to create a GL
texture from a surface we don't need to swap the R and B channels, as
the internal representation of the texture data will already have the
appropriate colors.
We also don't need to flip color channels when blitting from a texture.
Windows save in hardware_keycode an information which is not so low
level and some application require the hardware scancode.
As Windows provides this information save it in GdkEventPrivate
and provide a function to get this information.
For no Windows system the function return the hardware_keycode instead.

If there are already a window state event for a given window queued
when the window state is changed, drop that event and queue a new event
with a changed_mask based on the state before last event that was queue
without compression.

This avoids a bunch of allocations, and additionally it has better
cache behaviour, as we don't follow pointers to the separate GList
node memory areas during traversal.
From Christian Hergert:
This machine is a Retina mac book pro so I've been working on getting
GtkTextView (GtkPixelCache) up to our performance level on
X11/Wayland. I'm seeing a jump from about 43 FPS to about 50 FPS.

An pass_through window is something you can draw in but does not
affect event handling. Normally if a window has with no event mask set
for a particular event then input events in it go to its parent window
(X11 semantics), whereas if pass_through is enabled the window below
the window will get the event. The later mode is useful when the
window is partially transparent. Note that an pass-through windows can
have child windows that are not pass-through so they can still get events
on some parts.
Semantically, this behaves the same as an regular window with
gdk_window_set_child_input_shapes() called on it (and re-called any
time a child is changed), but its far more efficient and easy to use.
This allows us to fix the testoverlay input stacking test.

If we are disconnecting from a frame clock that has paused event
processing and hasn't issued a resume yet make sure we resume the
events or they will stay blocked forever.

This is required for the X backend GL integration. If the
window has a height that is not a multiple of the window scale
we can't properly do the y coordinate flipping that GL needs.
Other backends can ignore this and use the default implementation.
